Question

Complete the following equation:

${\mathrm{FeSO}}_4+{\mathrm{H}}_2\mathrm{O}\stackrel{}{\to }\mathrm{\_\_\_\_\_\_}$

Answer 1

Reaction of ferrous sulphate with water:

• When ferrous sulphate $\left({\mathrm{FeSO}}_4\right)$ reacts with water$\left({\mathrm{H}}_2\mathrm{O}\right)$, it forms ferrous hydroxide$\left(\mathrm{Fe}{\left(\mathrm{OH}\right)}_2\right)$ and sulphuric acid$\left({\mathrm{H}}_2{\mathrm{SO}}_4\right)$.
• $\underset{\mathrm{ferrous}\mathrm{sulphate}}{{\mathrm{FeSO}}_4\left(\mathrm{s}\right)}+\underset{\mathrm{water}}{2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{aq}\right)}\stackrel{}{\to }\underset{\mathrm{ferrous}\mathrm{hydroxide}}{\mathrm{Fe}{\left(\mathrm{OH}\right)}_2\left(\mathrm{s}\right)}+\underset{\mathrm{sulphuric}\mathrm{acid}}{{\mathrm{H}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)}$
