Question

A metal carbonate "X" on reacting with acid produces a gas , which when passed through a solution of "Y" gives the carbonate back. Identify X and and write the suitable reactions involved with it .

Answer 1

$\huge\mathtt{Answer:-}$

X is Calcium Carbonate (CaCO3)

Y is Calcium hydoxide [Ca(OH)2]

$\huge\boxed{CaCO3+HCl--->CaCl2+H20+CO2}$

$\huge\boxed{Ca(OH)2+CO2---->CaCO3+H2O}$
