Cooking soda is an alkali. It is sodium carbonate. And baking soda is sodium bicarbonate).

I: Difference between baking soda and cooking soda:

Cooking soda and baking soda are two different substances.

The main ingredient of practical soda is sodium carbonate, the molecular formula is Na3CO3, while the main ingredient of baking soda is NaHCO3, so the use of is not able to replace the baking soda.

The edible soda is steamed buns with, in the kitchen to do pasta, generally have to use baking soda, can be used for pasta fluffing agent.

Generally baking soda can be in the food additives store can buy baking soda. Baking soda can also be bought in chemical reagent points.

Two: baking soda:

The chemical name of baking soda is sodium bicarbonate (chemical formula: NaHCO3), commonly known as baking soda.

Baking soda is a weak base, widely used in the food industry and medicine, veterinary medicine, in foreign countries are more often used as livestock and poultry feed additives.

Baking soda is white fine crystals, solubility in water is less than soda. 270 ° C decomposition of sodium carbonate. It is a strong base and weak acid salt, the aqueous solution is weakly alkaline due to hydrolysis.

In medical use, sodium bicarbonate can neutralize gastric acid, dissolve mucus, reduce the viscosity of digestive juices, and strengthen the contraction of the stomach and intestines, play a stomach, acid suppression and enhance the role of appetite.

The human body is supposed to be weakly alkaline, and the pH of the internal environment should be between 7.35 and 7.45. If a person's constitution becomes relatively acidic, it can be adjusted through daily dietary adjustments and control.
