Question

4. Complete the reaction : Copper Sulphate (Cuso.) + Iron (Fe)-> + Copper ( Cu) ,1. Zinc Sulphate ( ZnSO2) ,

2.Magnesium Sulphate (MgSO) 3. Ferrous Sulphate ( FeSOA),4. None of these​

Answer 1

Answer: 3. Ferrous Sulphate ( FeSO₂),

Step-by-step explanation:

Copper Sulphate (CuSO₄) + Iron (Fe) → __Ferrous Sulphate ( FeSO₂)__ + Copper ( Cu)

Since we know the reactants and one of the products, we can work backward to discover what the other reactant may be.

As it is in the question, we can map the reactants and product:

Reactants Product

Copper Copper

Sulphate _____

Iron _____

This indicates that the product is a combination of Iron and Sulphate. Since Sulphate is of Valency two and Iron would want to match this valency, the likely product is Iron (II) Sulphate, commonly known as Ferrous Sulphate.
