Question

The formula of baking soda is ______.

विकल्प

• K₂CO₃

• KHCO₃

• NaHCO₃

• Na₂CO₃

Answer 1

The formula of baking soda is NaHCO₃.

Explanation:

Baking soda is the household name for the chemical compound sodium bicarbonate (or sodium hydrogen carbonate). Its chemical formula is NaHCO3, composed of a sodium cation (Na⁺) and a bicarbonate anion \[\ce{(HCO^-_3)}\]. When used in baking, it reacts with heat or acidic components to release carbon dioxide gas (CO₂), which makes dough rise and creates a soft, porous texture.
