Make no mistake! Baking soda, baking soda, and baking soda all have their own magical properties!

As an office worker, I just want to rest in bed when I get home every day, but when I see the dark floor and messy table, I can't help but feel bitter: housework is too tiring! Who can help me solve my problems? !

After complaining to a friend, she recommended me to buy "baking soda", which is known as a furniture cleaning expert. However, after surfing the Internet, I found that in addition to baking soda, there are also baking soda and baking soda. Their names are so similar that it is really hard to tell them apart.

What are the differences between them? Do they have the same functions? After a detailed study, I finally figured it out! Let me explain it to you in detail today~

1. Baking Soda

Baking soda , whose chemical composition is sodium bicarbonate (NaHCO3), is a white, fine crystal in powder form. It is soluble in water and its aqueous solution is weakly alkaline.

Baking soda is safe and non-toxic, can be decomposed naturally, can react with acid, and can also react with alkali. It is mostly used in industrial production, food preparation and daily cleaning in life. For example, in the pharmaceutical industry, baking soda can be used as a raw material for drugs to treat excessive gastric acid; in the rubber industry, baking soda can be combined with alum and other materials to produce uniform pores, which is used in the production of sponges and rubber products.

In the food industry, baking soda can produce a lot of gas after heating, and the chemical reaction formula is 2NaHCO3=Na2CO3+CO2+H2O, so it can be used as a food leavening agent for the production of bread, steamed buns and biscuits. When we make steamed buns, we also add a small amount of baking soda to the dough. The gas produced by the decomposition of baking soda will create many pores in the dough, making the steamed buns more fluffy and delicious.

In daily life, baking soda has many uses. For example, the water solution with baking soda can be used to soak fruits and vegetables to remove residual pesticides on the surface of fruits and vegetables ; apply baking soda on the stains on the range hood and let it stand for a while, then you can easily wipe off the oil stains ; in addition, baking soda can also be used for plant maintenance, washing clothes, removing odors from shoes , etc.

2. Soda

Soda , also known as "soda ash" or "baking soda", is a chemical compound composed of sodium carbonate (Na2CO3), which has one less hydrogen ion than baking soda and is more alkaline. Sodium carbonate is soluble in water and has a higher solubility than sodium bicarbonate (baking soda).

Anhydrous sodium carbonate is a white granular crystal with strong stability, not easy to decompose when heated, and strong hygroscopicity; sodium carbonate with crystal water is called hydrated sodium carbonate , which includes three types: sodium carbonate monohydrate (Na2CO3·H2O), sodium carbonate heptahydrate (Na2CO3·7H2O), sodium carbonate decahydrate (Na2CO3·10H2O). After heating, the hydrated sodium carbonate loses its crystal water and becomes anhydrous sodium carbonate.

In industrial applications, soda is mainly used in the production of chemical products, such as soap making, glass production, petroleum, textiles, etc. It is also used in the medical field, where soda can be used to treat excessive stomach acid.

In addition, baking soda can be used to make baking soda. Simply add carbon dioxide into the soda water solution to produce a chemical reaction to produce baking soda. The reaction equation is Na2CO3+CO2+H2O=2NaHCO3.

3. Baking Soda

Baking soda , whose chemical composition is sodium thiosulfate (Na2S2O3), has another name, "Haibo". Baking soda is a colorless and transparent crystal that is soluble in water and its aqueous solution is also weakly alkaline. After weathering and drying, the crystal water in the composition will be lost.

Baking soda is different from baking soda and baking soda. It is rarely used in daily life and is mainly used in laboratories and the chemical industry . Baking soda can react with silver bromide to form a complex. The reaction formula is AgBr+2Na2S2O3=NaBr+Na3〔Ag(S2O3)2〕, so in the photography industry, baking soda is often used as a fixer . The unexposed part of the film we take photos contains silver bromide. Baking soda reacts with silver bromide to remove AgBr, which can fix the developed part.

In addition, baking soda has strong reducing properties and can react with substances such as chlorine. Therefore, in the textile industry, baking soda is used as a dechlorination agent after fabric bleaching.

In general, although baking soda, baking soda and sodium bicarbonate have the same name, their chemical compositions are different. Among them, baking soda and baking soda are "close relatives" and can be connected through chemical reactions, while baking soda has little to do with the other two.

When I was shopping, I saw some merchants selling soda water that "can adjust the pH value of the human body". If a small amount of baking soda is added artificially, just look at it, but don't buy it! The pH value of the human body is stable and weakly alkaline, and there is no need to adjust it at all. Soda water is a pure IQ tax~ There is also a kind of natural soda water, which is rich in minerals and good for health, but natural soda water is relatively rare and often very expensive.

In fact, many chemicals seem to be difficult to understand and seem out of place in our daily lives, but if you change their names, you may find that "it turns out to be this." Knowing more about chemistry and using chemicals skillfully can make our lives more convenient~
