Question

Write balanced chemical reaction for the following reaction:

Aqueous solution of copper sulphate and potassium iodide react to form precipitate of cuprous iodide along with potassium sulphate and iodine gas.

Answer 1

When an aqueous solution of copper sulphate and potassium iodide reacts then there is a formation of a precipitate of cuprous iodide along with potassium sulphate and iodine gas. The balanced reaction can be written as,

$2{\mathrm{CuSO}}_4\left(\mathrm{s}\right)+4\mathrm{KI}{\left(\mathrm{s}\right)}_{}\to {\mathrm{Cu}}_2{\mathrm{I}}_2\left(\mathrm{s}\right)+2{\mathrm{K}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)+{\mathrm{I}}_2\left(\mathrm{g}\right)$.

Hence, the above reaction is a balanced chemical equation.
