Question

Reaction between magnesium and iron sulphate solution is a chemical double decomposition reaction.

• A. True
• B. False

Answer 1

The correct option is B False

Displacement reaction: A displacement reaction is a type of chemical reaction in which a more reactive metal displaces a less reactive metal from its salt solution.

The reaction between magnesium and iron sulphate solution is a chemical displacement reaction

.$$\begin{gathered} {\text{Mg(s) + FeSO}}_4\left(aq\right)\to {\text{MgSO}}_4(\text{aq) + Fe(s)} \\ \text{(Magnesium) (Iron sulphate) (Magnesium sulphate) (iron)} \end{gathered}$$

• Magnesium is more reactive than Iron as it lies above Iron in the reactivity series.
• Therefore, it displaces iron from iron sulphate solution.
• Hence, the given reaction is a displacement reaction.
• Therefore, the given statement is False.
