The difference between baking soda and baking soda is:
1. Different chemical formulas
Baking soda: sodium sulfate, the chemical formula is Na2S2O3, also known as sodium sulfite, Soda, hyposulfite (derived from its alias sodiumhyposulfite).
Baking soda: sodium bicarbonate, chemical formula NaHCO?, commonly known as baking soda.
2. Different properties
Sodium thiosulfate: It is a common thiosulfate, a colorless and transparent monoclinic crystal. Sodium thiosulfate is easily soluble in water and reacts with strong acid. Produces sulfur and sulfur dioxide.
Sodium thiosulfate is an antidote for cyanide. It is colorless, transparent crystals or crystalline fine particles; odorless and salty in taste; weatherable in dry air and deliquescent in humid air; aqueous solution shows weak alkaline reaction.
Baking soda: white fine crystals, less soluble in water than sodium carbonate. It is also an industrial chemical. The solid begins to decompose gradually above 50℃ to form sodium carbonate, carbon dioxide and water, and completely decomposes at 270℃.
3. Different uses
Baking soda: With the participation of rhodanese, it can combine with cyanide ions free in the body or bound to methemoglobin to form non-toxic sulfur Cyanate is excreted in the urine and resolves cyanide poisoning. In addition, it can combine with a variety of metal ions to form non-toxic sulfides that are excreted in the urine. It also has a desensitizing effect. Clinically used for the treatment of cyanide and nitrile poisoning, arsenic, bismuth, iodine, mercury, lead and other poisonings, as well as the treatment of skin pruritus, chronic dermatitis, chronic urticaria, drug eruptions, scabies, ringworm, etc.
Baking soda: Sodium bicarbonate is an acid salt formed after the neutralization of a strong base and a weak acid. It is weakly alkaline when dissolved in water. This property allows it to be used as a leavening agent in food preparation. After sodium bicarbonate is used, sodium carbonate will remain. If used too much, the finished product will have an alkaline smell.
Extended information:
In addition to baking soda and baking soda, there is another kind of soda, and its name is "soda".
Soda is the transliteration of Soda, and its chemical formula is Na2CO3. The scientific name is sodium carbonate, and the common name is soda ash, also known as soda ash or soda ash. The one with crystal water is called hydrated sodium carbonate.
Anhydrous sodium carbonate is white powder or fine particles that are easily soluble in water, and the aqueous solution is alkaline. It is highly hygroscopic and can absorb moisture in the air and form hard lumps.
Among the three types of soda, sodium carbonate is the most widely used. It is a very important chemical product and an important raw material for glass, soap, textile, papermaking, leather and other industries. It is also used in the metallurgical industry and water purification. It is also used in the manufacture of other sodium compounds.
