Question

Give a balanced chemical equation to prepare copper chloride using copper carbonate.

Answer 1

• During the preparation of copper chloride, carbon dioxide gas evolved.
• The balanced chemical equation to prepare copper chloride using copper carbonate is given below:

$$\begin{gathered} {\mathrm{CuCO}}_3\left(\mathrm{s}\right)+2\mathrm{HCl}\left(\mathrm{aq}\right)\to {\mathrm{CuCl}}_2\left(\mathrm{aq}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)+{\mathrm{CO}}_2\left(\mathrm{g}\right) \\ \mathrm{Copper}\mathrm{carbonate}\mathrm{Hydrochloric}\mathrm{acid}\mathrm{Copper}\mathrm{chloride}\mathrm{Water}\mathrm{Carbon}\mathrm{dioxide} \end{gathered}$$
