Question

what happens when nitric acid is added to egg shell??​

Answer 1

Manufacture and decomposition. Upon mixing of concentrated hydrochloric acid and concentrated nitric acid, chemical reactions occur. These reactions result in the volatile products nitrosyl chloride and chlorine gas: HNO3 (aq) + 3 HCl (aq) → NOCl (g) + Cl2 (g) + 2 H2O.

Nitric Acid reacts with egg shell to form calcium nitrate, carbon dioxide and water. Egg shell + Nitric Acid --------> Calcium Nitrate + Carbon dioxide + Water.

Answer 2

Nitric Acid reacts with egg shell to form calcium nitrate, carbon dioxide and water.

Egg shell + Nitric Acid --------> Calcium Nitrate + Carbon dioxide + Water.
