Question

Which substance is added to make cakes soft and spongy?

Answer 1

The white powder is baking powder.

The main ingredients are -

1.Baking soda (NaHCO3)

2.Mild edible acid( Tartaric acid)

Function of Baking soda is that it reacts with tartaric acid wo give CO2 and makes the cake spongy and .If only sodium hydrogencarbonate is used then the cake will be bitter to taste.

So the tartaric acid is used to neutralize the taste.
