Baking soda is sodium bicarbonate, also called acid sodium carbonate. It is an acid salt with small white crystals.

Baking soda can be used to make bread, make soda and as a fire extinguishing agent. The solid begins to gradually decompose above 50℃ to produce sodium carbonate, carbon dioxide and water, and completely decomposes at 270℃.

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.
