Question

How the respective nitrate salt be formed from the following? Give the equation

(c) Lead carbonate

Answer 1

Reaction Summary

• An acid reacts with appropriate metal carbonate and results in the formation of the required nitrate.
• It can be done using nitric acid$\left({\mathrm{HNO}}_3\right)$ which reacts with Lead carbonate $\left({\mathrm{PbCO}}_3\right)$ to form Lead nitrate $\left(\mathrm{Pb}{\left({\mathrm{NO}}_3\right)}_2\right)$, water$\left({\mathrm{H}}_2\mathrm{O}\right)$ and carbon dioxide$\left({\mathrm{CO}}_2\right)$.

Balanced Reaction

• The chemical equation is as follows:

${\mathrm{PbCO}}_3\left(\mathrm{s}\right)+2{\mathrm{HNO}}_3\left(\mathrm{aq}\right)\to \mathrm{Pb}{\left({\mathrm{NO}}_3\right)}_2\left(\mathrm{aq}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)+{\mathrm{CO}}_2\uparrow$
