Question

name two constituents of baking powder

Answer 1

Answer:

(a) Sodium hydrogencarbonate and tartaric acid.

(b) Baking powder is a mixture of baking soda and tartaric acid whereas baking soda is only sodium hydrogencarbonate.

(c) When baking powder mixes with water, then sodium hydrogencarbonate 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.
