Question

What is baking powder? Explain the action of baking powder in making of cake. Write equation of the
reaction involved and also give its two uses.​

Answer 1

Answer:

Baking powder is made up of a base, an acid, and a buffering material to prevent the acid and base from reacting before their intended use. Most commercially available baking powders are made up of sodium bicarbonate (NaHCO3, also known as baking soda or bicarbonate of soda) and one or more acid salts.

Explanation:

On mixing baking powder with water, which is present in the dough prepared for baking a cake or bread, sodium hydrogen carbonate reacts with tartaric acid to evolve carbon dioxide gas. The carbon dioxide gas gets trapped in the wet dough and bubbles out slowly, and the cake becomes soft and spongy.
