What is the common name for the chemical compound Sodium bicarbonate?

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. Baking powder.

Sodium bicarbonate is most commonly known as baking soda—a household staple used as a leavening agent in baking, cleaning aid, and mild antacid. Its chemical formula is NaHCO₃, and it releases carbon dioxide when reacting with acids such as vinegar or lemon juice, which makes dough rise . Although sometimes confused with baking powder, baking soda is pure sodium bicarbonate, whereas baking powder contains added acid salts and starch .
