Baking soda is very common in daily life. In addition to eating, it is also loved by people for its superior decontamination ability. There are even rumors that baking soda is omnipotent and can “clear everything”. Is this true?
Baking soda is indeed a good helper in our lives, but it is not as magical as it is said in rumors. Some people choose to use vinegar and white vinegar to remove rust. In fact, this is useless. Baking soda is alkaline, and the composition of rust is iron oxide. Iron oxide and alkali can not react, so it does not have the function of removing rust. Some people choose to use vinegar to dissolve rust, but the concentration of acetic acid in white vinegar is lower. It is also not realistic to remove rust with white vinegar. If you mix the two, not only can you not remove the rust, but the salt may also cause the rust rate to increase. Therefore, if you want to remove rust, it is best to remove it by sandpaper, grinding wheel, etc., or soak it with a liquid such as dilute sulfuric acid with a high concentration of acetic acid to react with iron oxide to remove rust.
The statement about the removal of scale and urinary scale from baking soda is even more exaggerated. The components of the scale are mainly calcium carbonate, calcium sulfate, magnesium carbonate, magnesium sulfate, calcium chloride, magnesium chloride, etc., the components of the urinary scale are mainly carbonates, phosphates, ammonium salts, etc., which do not react with the alkali. Baking soda does not have this ability to clear.
In addition, some people use baking soda to remove blackheads, saying that as long as the baking soda and water are mixed at a ratio of 1:10, the blackheads can be cleaned by applying a cotton pad to the nose. This practice is not advisable. Blackheads are pore plugs, and human skin is slightly acidic. The secretions of the skin create a mild acid environment that is not conducive to bacterial growth, keeping the skin healthy. If the alkaline baking soda is applied to the skin, it will destroy the skin’s unique micro-acid environment, not only can not remove the blackheads, but also easily dry and dehydrate the skin, and even irritate the skin to cause allergies, infections and the like. Therefore, we must choose a scientific and reliable method when skin care, we must not easily try the network transmission method, so as not to increase the burden on the skin.
Although many online legends are not reliable, baking soda does have a certain use in the food and pharmaceutical industries. First of all, baking soda can be used as a leavening agent for making pasta. Adding a small amount of baking soda in the dough can not only make the food softer, but also neutralize the sour taste in the flour and improve the taste of the pasta. Second, baking soda has an anti-itch effect. After being bitten by mosquitoes, apply some baking soda powder to quickly relieve itching and prevent it from being bitten again. Third, baking soda can eliminate the smell in the refrigerator, keep the food fresh, and also absorb the smell in the shoes to prevent the production of fungi. Fourth, baking soda can be used to relieve indigestion and heartburn and reduce the symptoms of gastric irritation caused by oral stomach medicine. In addition, baking soda can quickly neutralize stomach acid, and has a certain analgesic effect on gastric ulcer and stomach pain. However, it should be noted that since personal physique and physical condition are different, it is recommended to consult a doctor before drinking baking soda.
Although baking soda is powerful, it is not omnipotent. For all kinds of statements on the Internet, we must learn to distinguish between true and false, and must not blindly follow the trend.
