Explanation:
To distinguish between lead carbonate and zinc carbonate, we will add hydrochloric acid to both the solutions. The reaction for these compounds with HCl is given by the equation:
\begin{lgathered}PbCO_3(s)+2HCl(aq.)\rightarrow PbCl_2(s)+CO_2(g)+H_2O(l)\\\\ZnCO_3(s)+2HCl(aq.)\rightarrow ZnCl_2(aq.)+CO_2(g)+H_2O(l)\end{lgathered}PbCO3(s)+2HCl(aq.)→PbCl2(s)+CO2(g)+H2O(l)ZnCO3(s)+2HCl(aq.)→ZnCl2(aq.)+CO2(g)+H2O(l)
White precipitate of lead chloride will be formed in the lead carbonate solution but no precipitate will be formed when zinc carbonate is reacted with hydrochloric acid.
hope it helps you....
