Baking soda, namely sodium bicarbonate, is an acid salt with the chemical formula of NaHCO3. White fine crystals, less soluble in water than sodium carbonate. It is also an industrial chemical.

People usually only know that it can be used to make bread, soda and fire extinguishing agent. In fact, it has the following little-known uses.

Baking soda is a weak base and an absorptive antacid. After oral administration, it can quickly neutralize gastric acid, with rapid action and short duration, and has many shortcomings such as producing carbon dioxide. As an antacid, it should not be used alone, and it is often used together with calcium carbonate or magnesium oxide to form Sibiside powder.

Extended data:

In the mass production of steamed bread, fried dough sticks and other foods, soda powder melt water is often mixed into noodles, which is decomposed into sodium carbonate, carbon dioxide and water after heating, and carbon dioxide and water vapor overflow, which can make the food more fluffy and sodium carbonate remains in the food. Too much baking soda can be tasted in steamed bread.
