Hii mate,
A solution reacts with crushed egg-shells to give a gas that turns limewater milky. Identify the solution . Also give the appropriate chemicalreaction. Egg shells contains calcium carbonate, which on reaction with HCl liberates CO2 gas which turn lime water to milky.
I hope it helps you.
Please mark me answer as brainlist.

ANSWER :
HCl
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
CO₂ + Ca(OH)₂=>CaCO₃ + H₂O ( limewater turns milky )
