Question

A person found that the cake prepared is hard and small in size. Name the ingredient missed during the preparation.

Answer 1

1. During the making of cakes and bread, sodium bicarbonate (${\mathrm{NaHCO}}_3$) is added to make it soft and fluffy.
2. ${\mathrm{NaHCO}}_3$ acts as a leavening agent as it when added to water, reacts with acid present and releases carbon dioxide (${\mathrm{CO}}_2$) to give a spongy texture to the cakes and bread.
3. Hence, sodium bicarbonate (${\mathrm{NaHCO}}_3$) is the ingredient missed during the preparation.
