Question

Give reason:

a.baking soda is used to make cakes and bread soft and spongy

b.baking soda helps in extinguishing fire

Answer 1

.a. Baking powder is mixed with the flour. When water is added to this flour to make dough, baking powder undergoes a chemical reaction during which carbon dioxide gas is produced. This carbon dioxide gas gets trapped into the dough and bubbles out which causes the cake to rise making it soft and spongy.

b.When sodium bicarbonate (baking soda) is heated, it becomes sodium carbonate. In this process water and carbon dioxide is released. The CO2 starves the fire of O2.
