QuesTion :-

What happens when nitric acid is added to egg shell?

AnswEr :-

We can see a brisk effervescence, a gas which turns lime water milky and extinguishes; and a glowing splinter is evolved.

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

$\sf {Equation :-}\\\\\\\mathrm {CaCO_{3} \ [s] + 2HNO_{3} \ [aqu] \longrightarrow Ca(NO_{3})_{2} \ [aqu] +CO_{2} \ [g] + H_{2}O \ [l]}$
