Answer 1

$\huge\mathfrak\pink{Answer}$

A) Sodium bicarbonate commonly known as baking soda is a chemical compound with the formula NaHCO3. It is a salt composed of a sodium cation and a bicarbonate anion. Sodium carbonate can be obtained by heating baking soda, recrystallization of sodium carbonate gives washing soda. It is also called basic salt.

B) Baking soda is converted to a baking powder by adding tartaric acid and starch to the baking soda. Baking soda is basic in nature and bitter in flavor. As the baking soda reacts to the batter that is produced, it neutralizes the bitter taste of the baking powder to give rise to carbon dioxide and water as moisture.

C) 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.

D) Plaster of Paris (POP) should be stored in a moisture-proof container because Plaster of Paris, a powdery mass, absorbs water (moisture) to form a hard solid known as gypsum.
