Subjective Type

(a) What is "baking powder"? How does it make the cake soft and spongy? (b) In addition to sodium hydrogencarbonate, baking powders contain a substance X. Name the substance X. What is the role of substance X in the baking powder?

Solution

(a) Baking powder is a mixture of baking soda and tartaric acid. When baking powder mixes with water, then sodium hydrogen carbonate reacts with tartaric acid to evolve carbon dioxide gas which gets trapped in the wet dough and bubbles out slowly making the cake soft and spongy.

(b) Substance X is tartaric acid. It reacts with any sodium carbonate formed and neutralise it otherwise cakes and bread will taste bitter.
