Give the missing product Mg + Fe1Cl3 ---> Fe + _?_

The missing product : MgCl₂

Given

The reaction between Mg and FeCl₃

Required

The missing product

Solution

This reaction is a single replacement reaction

Occurs when one element replaces another element in the compound. The more active element will replace the less active element. The activity of this element can be seen from the voltaic series

Li-K-Ba-Ca-Na-Mg-Al-Mn- (H2O) -Zn-Cr-Fe-Cd-Co-Ni-Sn-Pb- (H) -Cu-Hg-Ag-Pt-Au

Mg is located to the left of Fe in the voltaic series so that it can replace Fe from its compound

General formula :

A + BC ⇒ AC + B

So the reaction :

3Mg + 2FeCl₃ → 2Fe + 3MgCl₂
