2, baking soda and white vinegar are mixed with water, and they are used to protect skin, which can make your skin smoother and whiter. White vinegar can help soften keratin, so it can help remove dead skin on the skin and make your skin feel smoother.

Be sure to pay attention to the dosage when using, and never use white vinegar with too high concentration, otherwise it may cause certain damage to your skin. In addition, if you want to use baking soda, you should also control the dosage and blend it with water in advance.

Before going to bed every day, you can wash your hands with hot water, and then soak your hands with a mixture of the two, so that your skin will become good and save money for a long time.

3, baking soda can be used instead of detergent, and the washing effect is very good. This is because most of the oil stains belong to esters, which are insoluble in water, so it is difficult to clean them simply by washing with water. However, esters can be hydrolyzed in the alkaline environment of baking soda solution to obtain sodium carboxylate, which is dissolved in water, thus achieving the effect of removing oil stains.

4. You can cook the towel with the solution of baking soda. The high temperature environment is conducive to the reaction between oil and baking soda. In addition, you can also soak the towel in white vinegar to react the carbonate insoluble in water, and finally wash it with clean water, and the towel will become soft.

Proverbs 1: Toothpaste and baking soda can easily decontaminate.

Baking soda, also known as sodium bicarbonate, plays an important role in many fields, such as medicine, cleaning, food, beauty, chemical industry, etc. According to folk legend, putting a little baking soda in toothpaste when brushing teeth can make teeth whiten quickly, so is this true or false? We need to analyze and judge the physical and chemical properties of baking soda itself? .

First, adding baking soda to toothpaste can make baking soda particles directly rub teeth and help clean tartar; Secondly, baking soda has a slight corrosive effect, and it will present a weak alkaline environment when it meets water, while the environment in which tartar grows is weak acid. Therefore, adding baking soda to toothpaste can destroy the environment in which tartar grows, thus playing a role in removing tartar.

But there are some points that deserve our scrutiny.

First of all, the effect of baking soda can be achieved in many toothpastes on the market, and the effect is not worse than baking soda. Toothpaste+baking soda does not necessarily have the effect of 1+ 1=2, even because of the ratio or other factors, it is better to believe the research results of regular toothpaste manufacturers than to make special toothpaste with its own formula.

Secondly, I believe you have some experience that the whitening effect of brushing teeth is not obvious. The whitening mechanism of baking soda is similar to that of toothpaste, which is helpful for cleaning tartar, but it has no obvious effect on the pigment deeply attached to the tooth surface, so it is impossible to talk about rapid whitening.

Some methods that can really achieve rapid whitening, including cold light whitening and tooth bleaching, use a completely different mechanism from baking soda. They use high-intensity light with a specific wavelength to trigger free radicals to oxidize and reduce pigment molecules to achieve rapid whitening. [4]? .

It seems that it is difficult to achieve satisfactory results simply by hoping to use baking soda to remove tartar for rapid tooth whitening. Friends who want to whiten their teeth had better go to a regular dental hospital instead of relying on some so-called folk remedies? [4]? .

Myth 2: Baking soda can remove rust and scale.

Baking soda, that is, sodium bicarbonate, is an acid salt, which is weakly alkaline after being mixed with water. It is a crystalline white solid, but usually it is a fine powder with a slightly alkaline taste.

Because the components of scale are calcium carbonate, magnesium carbonate, magnesium hydroxide, etc., these components will not react with alkali, and only acid can remove them, so baking soda can not be used to remove scale.

In addition, it is unscientific to say that baking soda and white vinegar can remove rust. The composition of rust is iron oxide, which does not react with alkali, so baking soda can't remove rust. Although acetic acid can slowly dissolve rust, the concentration of acetic acid in white vinegar is only 3%-5%, which basically has no rust removal effect.
