Question

suman placed an egg in a beaker containing a liguid. he found bubbles forming on the shell after some time what could the nature of the liquid be? which gas was formed?

Answer 1

If you soak this egg shell in vinegar(which is about 4% acetic acid), you start a chemical reaction that dissolves the calcium carbonate shell. The acetic acid reacts with the calcium carbonate in the egg shell and releases carbon dioxide gas that you see as bubbles on the shell.

So answer is vinnegar which is acetic acid.
gas is carbon dioxide.
