Question

what happens when egg shell is added to nitric acid​

Answer 1

Answer:

Egg shell is made of calcium carbonate. We know that when calcium carbonate reacts with nitric acid, it gives carbon dioxide, calcium nitrate and water. Same reaction happens when nitric acid is poured over egg shell.

CaCO3 + 2HNO3 → Ca(NO3 )2 + CO2 + H2O

Answer 2

Egg shell is composed of Calcium Carbonate (CaCO3)

Hence, when Nitric acid is added to it, following reaction takes place.

CaCO3 + 2HNO3 ----> Ca(NO3)2 + CO2 +H2O
