2: Pour more than half a bottle of cool boiled water in a transparent glass bottle and put in a spoonful of sugar. Stir with chopsticks.
3: Pour baking soda, into the glass bottle. Stir with chopsticks, and put two drops of fruit flavor in the bottle.
4: Pour in the lemon fruity acid, immediately put the cap on the bottle, a bottle of soda is made.
Marble soda:
Making soda and understanding the effect of pressure on the solubility of gases.
Equipments:
1 marble soda bottle 1 cup 1 sugar cube 2 pcs
3 baking soda tablets 40ml vinegar 160ml boiling water
Steps:
1. Put 2 sugar cubes in the cup and add 160ml water and 40ml vinegar, stir until the sugar is dissolved and then pour it into the marble soda.
2. Take 3 baking soda tablets and put them into the marble soda bottle, then immediately press the mouth of the bottle with your thumbs, shake it for a few times, and then turn the bottle upside down, so that there is no air leakage.
3. When your thumb feels inflated, release your thumb and the marbles will block the mouth of the bottle.
4. About half an hour after the baking soda is dissolved, you can press the marble down and pour out the soda to taste.
2, homemade soda
Raw material recipe (a bottle) 1.5 grams of baking soda citric acid (or tartaric acid) 1.5 grams of granulated sugar, a little Juice
Methods of production with a clean bottle of soda, the cold water poured into the bottle, do not be too full, add some sugar and a certain amount of fruit juice. Then put 1.5 grams of baking soda, and finally 1.5 grams of citric acid (or tartaric acid), and immediately cork the bottle tightly, and tie the cork tightly with a thin rope or aluminum wire to prevent the soda from rushing out. Gently shake the bottle, the bottle produces a large number of bubbles, constantly rolling up and down, after about 20 minutes you can drink.
If you sweat a lot of comrades, you can not make juice soda but salt soda, the same way, only the sugar and fruit juice into the right amount of salt can be.
In case of emergency, it is better to wrap the soda bottle with a cloth when making soda.
Method of production Baking soda and citric acid (or tartaric acid), through the chemical reaction to produce a large amount of carbon dioxide, carbon dioxide in the pressure under the action of a large number of dissolved in water. Reduce the pressure, carbon dioxide will run out of water, when drinking soda, the stomach and intestines do not absorb carbon dioxide, carbon dioxide from the mouth to run out to take away a lot of heat, so that people feel cool.
Soda is made from mineral water or drinking water sterilized by boiling and ultraviolet irradiation and filled with carbon dioxide. It is a carbonated beverage containing carbon dioxide. Soda is made in factories by pressurizing the water so that the carbon dioxide gas is dissolved in the water. The more carbon dioxide dissolved in the soda, the better the quality. For sodas sold on the market, there is about 1 volume of carbon dioxide dissolved in 1 volume of water to 4.5 volumes of carbon dioxide. Some sodas contain carbon dioxide in addition to adding the right amount of sugar, fruit juice and flavor.
Carbon dioxide from the body, can take away some heat, so drink soda can quench the thirst. Drinking chilled soda, because the temperature of the soda is lower, more dissolved carbon dioxide (0 ℃, the solubility of carbon dioxide than 20 ℃, 1 times larger), there are more carbon dioxide to be discharged from the body, can take away more heat, so it is more able to reduce the temperature of the stomach and intestines. Therefore, never drink a lot of chilled soda, so as not to produce a strong cold stimulation of the stomach and intestines, causing stomach cramps, abdominal pain, and even induced gastroenteritis. In addition, too much soda will dilute the gastric juice, reduce the digestive ability and bactericidal effect of gastric juice, affect the appetite, and even increase the burden on the heart and kidneys, causing discomfort.
Homemade sodas can also be made in the laboratory and at home. Take a scrub clean soda bottle, bottle add 80% of the volume of cold boiled water, then add sugar and a small amount of fruit flavor, then add 2 g sodium bicarbonate, stirring to dissolve, and quickly add 2 g citric acid. And immediately press the cap of the bottle tightly, so that the generated gas can not escape, but dissolved in the water. Place the bottle in the refrigerator to cool down. After removing, open the cap and drink.
