Question

Explain with the help of the equations, how the following salts can be prepared in the laboratory:

(b) Copper sulphate

Answer 1

Reaction Summary

• By neutralization reaction, copper sulphate$\left({\mathrm{CuSO}}_4\right)$ can be prepared.
• It can be done using appropriate acid, like sulphuric acid$\left({\mathrm{H}}_2{\mathrm{SO}}_4\right)$ which reacts with copper oxide$\left(\mathrm{CuO}\right)$ to form copper sulphate$\left({\mathrm{CuSO}}_4\right)$ and water$\left({\mathrm{H}}_2\mathrm{O}\right)$.

Balanced Reaction

• The chemical equation is as follows:

$\mathrm{CuO}\left(\mathrm{s}\right)+{\mathrm{H}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)\to {\mathrm{CuSO}}_4\left(\mathrm{aq}\right)+{\mathrm{H}}_2\mathrm{O}$
