Question

Give the balanced equation for the following reaction:

Copper sulphate from copper and concentrated sulphuric acid.

Answer 1

1. When $1$ mole of $Cu$ reacts with $2$ moles of concentrated sulphuric acid ($H_{2}S{O}_4$) then $1$mole of Copper sulphate ($CuS{O}_4$) and$1$ mole of Sulphur dioxide ($S{O}_2$) and$2$ moles of water are produced.

Balanced chemical reaction:

$\text{Cu}\left(\mathrm{s}\right){\text{+ 2H}}_2{\text{SO}}_4\left(aq\right)\stackrel{}{\to }{\text{CuSO}}_4\left(\mathrm{s}\right){\text{+ SO}}_2\left(\mathrm{g}\right){\text{+ 2H}}_2\text{O}\left(\mathrm{l}\right)$
