Write down what happens when iron, copper and magnesium metals are added to an aqueous solution of Zinc sulphate ?

Explanation

To understand what happens when iron, copper, and magnesium metals are added to an aqueous solution of zinc sulfate, we need to consider the reactivity series of metals. The reactivity series ranks metals based on their ability to displace other metals from solutions of their salts.

### Step-by-Step Solution:

1. **Identify the Reactivity of Metals**:
- The reactivity series from most reactive to least reactive includes: Magnesium (Mg), Zinc (Zn), Iron (Fe), and Copper (Cu).
- In this series, magnesium is more reactive than zinc, which is more reactive than iron and copper.
