Gas A is bubbled through slaked lime when a white precipitate is formed. On prolonged bubbling the precipitate is dissolved. On heating the resultant solution, the white precipitate appears with evolution of gas B. The gases A and \(\mathrm{B}\) respectively are
According to the question, \(\mathrm{Ca}(\mathrm{OH})_{2}+\mathrm{CO}_{2} \rightarrow \underset{\text { White ppt }}{\mathrm{CaCO}_{3}}+\mathrm{H}_{2} \mathrm{O}\) \(\begin{aligned}& \mathrm{CaCO}_{3}+\mathrm{H}_{2} \mathrm{O}+\mathrm{CO}_{2} \rightarrow \mathrm{Ca}\left(\mathrm{HCO}_{3}\right)_{2} \\& \mathrm{Ca}\left(\mathrm{HCO}_{3}\right)_{2} \stackrel{\Delta}{\longrightarrow} \mathrm{CaO}+\mathrm{H}_{2} \mathrm{O}+2 \mathrm{CO}_{2}\end{aligned}\) Hence, the gas \({\text{A}}\,\,{\text{and}}\,\,{\text{B}}\) are \(\mathrm{CO}_{2}\) and \(\mathrm{CO}_{2}\) respectivley.
