Time flies like a horse, and one day passes. We must have a lot of feelings, so we have to keep a good diary. So how to write a beautiful diary? The following is the observation diary of soaking eggs in white vinegar that I collected for your reference. I hope it can help friends in need. Observation Diary of Eggs Soaked in White Vinegar 1

Today I was very interested and wanted to see what eggs soaked in vinegar would look like. When you peel a preserved egg, you can see that the egg white is dark green with some patterns, and the yolk is orange, and it tastes tender. When you peel a salted duck egg, you can see that the egg white inside is very white, and the yolk is golden yellow. Yes, the color is very bright and looks beautiful.

I took out two eggs from the refrigerator, one raw and one cooked. I carefully put the two eggs into two bottles filled with nine-degree white vinegar and quietly waited for their changes. Five minutes passed. Both of them floated, and then many small bubbles appeared, as if they were taking a hot spring bath. They seemed to say to me: "This hot spring is so comfortable. Look, I'm covered in bubbles." It’s so fun!” Very interesting and I’m looking forward to more variations from Juedan.

The next day, I looked at my two vinegar eggs again. The bubbles on the vinegar eggs had not reduced, and I found that the shells of the raw eggs It had completely fallen off, revealing its snow-white belly, which was soft to the touch. But only two-thirds of the shell of the cooked egg has fallen off, and it still feels hard to the touch. I thought to myself: You have to hurry up and come on! So why do raw eggs "undress" when soaked in vinegar? I got the answer on Baidu: Because vinegar contains a lot of "acid" substances, and "acid" has a corrosive effect, the egg shells can become soft and peel off.

On the third day, when I looked at the two vinegared eggs again, I found that the cooked vinegared eggs had completely rounded them out. The chubby body was shown to me, and I couldn't help but smile. When I turned my attention to the raw vinegar eggs, I couldn’t help but be surprised! I saw that the vinegar egg in the cup had become transparent, and the egg liquid inside could be seen flowing. I picked up the cup and looked carefully. It turned out that the vinegar egg had been corroded and only a thin film was left. I excitedly took the vinegar egg out of the cup. The vinegar egg felt very elastic and jumped around in my hand as soon as I took it out. It was so cute!

This observation brought me a lot of fun, just as Mr. Lu Xun said: "A drop of water, viewed with a microscope, is also a big world." Observation Diary of Eggs Soaked in White Vinegar 2

I heard that eggs soaked in white vinegar will become soft and transparent. Is this true? I decided to try it myself.

As soon as I got home, I couldn't wait to open the refrigerator, carefully took out the eggs, put them gently in a transparent cup, and slowly poured vinegar. Hey, the egg was immediately surrounded by thousands of small bubbles, floating little by little, swaying, sinking and floating, like a drunken drunkard. After about a minute, the egg slowly poked its head out, revealing a small tip the size of a fingernail.

What will it look like? When I got up the next day, I ran to look at the eggs before I even washed my face. It was still floating, but there was a brown film floating on it. Is this an eggshell? I looked carefully and the eggshell was still there! I touched it lightly with chopsticks, and scratches were made on the surface of the eggshell. , revealing the protein inside. I continued to scratch the surface of the eggshell with my chopsticks. More of the egg white was exposed, and the egg turned into a big painted face. The white vinegar also became cloudy, so I changed it once.

Today, the eggs performed a transformation trick for us. The hard shells turned into tiny pieces of foam, and the small bubbles also When it gets smaller, the egg becomes transparent, like crystal clear amber or a water balloon. I pressed it gently with my hand, and it jumped like a naughty crystal baby, and like a diving ballet, sometimes jumping out of the water, sometimes sinking into the bottom of the water.

I fished the egg out of the vinegar and held it carefully in my hand, for fear of breaking it. I observed carefully that the egg became thin and transparent, like an inflated balloon that could be popped by blowing. We can still vaguely see the egg yolk inside. I asked my mother: "Why do eggshells become crystal clear?" My mother said: "Raw eggshells contain calcium carbonate, which reacts with acetic acid to form soluble calcium acetate and generate carbon dioxide gas." It turns out that there are thousands of eggshells around it. Tens of thousands of small bubbles are carbon dioxide gas. I also know that eggs soaked in white vinegar can not only cure coughs, but also beautify the skin! Observation Diary of Eggs Soaked in White Vinegar 4

Today, I had a sudden thought: salted eggs are salty, preserved eggs are transparent, so what are vinegar eggs like? Woolen cloth? I rushed home at a sprint speed of 100 meters, quickly took an egg from the refrigerator, gently put it into a cup, and then poured in white vinegar with a concentration of 9 degrees.

Ten minutes later, I saw that the eggshell was covered with small bubbles, like small pearls. It's really amazing! From then on, I began to look forward to it for a long time.

Early this morning, my mother woke me up: "There is a layer of powder on the eggshell. !" When I heard this, I lost all my sleep. I really wanted to know what would happen to eggs soaked in vinegar. I immediately got up and ran to the living room. I went to the "little egg" and observed it carefully. I found that the egg "floated" and there was a layer of powder wherever the vinegar did not reach it. I asked my mother: "Where did those powders come from? Why are they there?" My mother said: "These powders should be the calcium in the eggshells, which separate when it encounters vinegar." I nodded and said, "That's it. "I also saw that the small bubbles that were originally attached to the egg shell were scattered to every corner of the cup and left the little egg base camp.

In the afternoon, I looked at my "little balls" and found that the air inside seemed to be solidified. , there is only a little bit of bubbles left inside. I gently touched the egg with my finger, and I found that it softened and turned into a small ball. When I pressed it, a hole was dented, which was very fun. There is more powder on the eggshell, forming a circle on the eggshell, like a small hole. I think this "jealousy" experiment is getting more and more interesting.

I went on a trip on the 4th and immediately ran to see my "little balls" when I came back. . I was pleasantly surprised to find that it absorbed all the vinegar! It turns out that the "little balls" also have the function of absorbing water. I carefully observed the eggshell. As soon as you touch it, its powder sticks to your hand, leaving only a white patch where it was touched. When I looked at the whole egg, it was almost the same as a well-fed little fat pig. I was surprised by how much it had changed in two days!

I searched for the reason for the powder in the vast amount of information. As a result, I learned that eggs contain calcium carbonate that dissolves and leaves the soft membrane inside the eggshell, so eggs soaked in vinegar will become softer. So there will be such powder on the egg shell. Observation Diary of Soaking Eggs in White Vinegar 6

Today, Teacher Deng gave us a special assignment: let us put a clean, fresh raw egg Put the eggs in a glass filled with 9 degree white vinegar and observe what strange changes will happen to the eggs.

So, I returned home in the evening, and my father and I searched the Internet for how to make vinegared eggs, and then we started making vinegared eggs. I took out a fresh raw egg, cleaned it, and put it on the table to prepare.

We first took a graduated glass, poured 180 ml of water into it, and then poured the water in the glass into another glass. Then use a ruler to measure the height and mark it, and then pour the water out of the cup. Finally, just pour 9-degree white rice vinegar into the cup. When the water level rises to the mark, you can put the eggs in.

When I first put the egg in, there were a lot of bubbles on the egg, like a crystal clear jewel. After a while, the egg actually floated, but it sank not long after. Then he floated up again, then sank again, unconscious in the water, as if he had lost his way. After a while, the egg began to rotate in the water, and kept spitting out bubbles while rotating. I didn’t expect that the changes in the vinegar egg would be so miraculous. I’ll have to observe it tomorrow!

As soon as I got home today, I couldn’t wait to run to the dining table to observe how my jealous egg was doing. Sure enough, the performance of the vinegar egg did not disappoint me. After a day, the vinegar egg was much bigger than yesterday, and there were more and more bubbles on the water surface. This means that my vinegar egg is almost complete, and now I only need to observe it for one more day and it's done.

Sunny Thursday, September 29

Today I came home and found that the vinegar eggs were a little transparent, so at night I used chopsticks to soak the eggs that had been soaked in 9 degree white vinegar. The shell was punctured, and a red and golden egg yolk flowed out. I used chopsticks to pick out the deflated egg shells from the cup, put them aside, and then stirred the egg yolks, egg whites and white vinegar evenly to form a vinegar-egg liquid.

Then my mother poured some vinegar and egg liquid into a small bowl, and my father poured some sweet honey into it. I couldn't help but take a small sip. The taste was sour and sweet. Unfortunately, I wasn't used to this taste yet, so I only drank a little.

This is truly an unforgettable experience! Observation Diary of Soaking Eggs in White Vinegar 7

Today I am going to do a small experiment on soaking eggs in vinegar. I took out a red-shelled egg from the refrigerator and found a glass. In order to observe it more clearly, I decided to soak the egg in white vinegar.

I first wash the eggs, put them in a glass, and then pour the white vinegar in until the eggs are covered. I stared at the vinegar-soaked egg through the glass. Suddenly, something magical happened. The egg put on a "bubble suit"!

I curiously touched the eggshell with my fingers, and a slight numbing sensation came over me. Mom said it was a chemical reaction between eggshells and white vinegar. This is so interesting, what happens next? It’s really exciting!

As soon as I opened my eyes in the morning, I went to see the pickled eggs in vinegar. Look, it has gained a lot of weight. The color of the eggshell is not as bright as yesterday. The mouth of the glass is filled with bubbles and a layer of brown sticky stuff has formed. This may be the broken eggshell.

I put my index finger into the glass and lightly ordered the pickled eggs in vinegar. Hey, it's amazing. The originally hard egg shell has become a little soft now. I carefully placed the pickled egg in vinegar on the desk, waiting to see how it will look tomorrow.

December 3, 20xx

The egg shell that was still soft yesterday has completely turned into a soft and translucent film today. The egg has doubled in size!

The hard eggshell is gone. Where did it go? The size of the eggs will increase. What's going on? With my head full of questions, I checked the information online. The reason why the eggshell softens until it disappears is because the acetic acid contained in the vinegar dissolves the calcium carbonate, the main component of the eggshell, and the bubbles that emerge in the eggshell are carbon dioxide bubbles produced by the dissolution reaction. As for the egg's volume doubling in size, it is caused by osmotic pressure. When the concentrations of substances on both sides of the film are not equal, osmotic pressure will occur, and the water in the substance on the side with a lower concentration will penetrate the film and penetrate into the other side, so that the concentrations of substances on both sides of the film are equal. The sticky protein concentration inside the egg is relatively high. After the eggshell becomes thin, under the influence of osmotic pressure, the water in the white vinegar penetrates the translucent film formed after the eggshell dissolves and enters the inside of the egg, thereby stretching the entire egg. .

Ah, so that’s what happened! Through this small scientific experiment of soaking eggs in white vinegar, I learned about the wonders of chemical reactions and experienced the joy of doing it.

At night, put the egg on the flashlight and shine it. The egg is like a night pearl, very bright.
