Question

A solution react with crush egg cell that turn lime water milky the soution contain

Answer 1

it should contain carbon dioxide (CO2)

Answer 2

Question :

A solution produces a gas by reacting with egg shells, which turns lime water to milky. What will happen in this solution?  

ANSWER :

Hydrogen chloride , carbon dioxide

Lime water turns milky and hence the gas is carbon-dioxide.

We already know that egg shells contain calcium carbonate .

Hence the only thing that can displace is HCl .

Thus the answer is HCl as only an acid can perform the above reaction and displace the calcium carbonate to liberate an acidic gas.

Reaction :

CaCO₃ + 2HCl → CaCl₂ + H₂O + CO₂
