Question

Write the balanced equation for the action of Iron (II) sulphate on ammonium hydroxide solution.

Answer 1

• When ammonium hydroxide reacts with iron (II) sulfate the product formed will be iron hydroxide and ammonium sulfate.

$$\begin{gathered} {\mathrm{FeSO}}_4\left(\mathrm{aq}\right)+2{\mathrm{NH}}_4\mathrm{OH}(\left(\mathrm{aq}\right)\to {\left({\mathrm{NH}}_4\right)}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)+\mathrm{Fe}{\left(\mathrm{OH}\right)}_2\left(\mathrm{s}\right) \\ \mathrm{Iron}(\mathrm{II})\mathrm{sulphate}\mathrm{Ammonium}\mathrm{hydroxide}\mathrm{Ammonium}\mathrm{sulphate}\mathrm{Iron}\mathrm{hydroxide} \end{gathered}$$

• It is a balanced chemical reaction as the no. of atoms on both sides of the reaction equation are equal.
• It is an example of a double displacement reaction.
