What's the balanced equation for Iron and copper (II) sulfate solution.

Georgia [21]

Answer:

2Fe + 3CuSO₄ → Fe₂(SO₄)₃ + 3Cu

Explanation:

The reactants are:

Iron = Fe

Copper (II) sulfate solution = CuSO₄

The reaction is given as:

Fe + CuSO₄ → Fe₂(SO₄)₃ + Cu

This is a single displacement reaction;

Now let us balance the equation;

aFe + bCuSO₄ → cFe₂(SO₄)₃ + dCu

Conserving Fe;

a = 2c

Conserving Cu;

b = d

Conserving S;

b = 3c

Conserving O;

4b = 12c

let b = 1;

c = $\frac{1}{3}$

d = 1

a = $\frac{2}{3}$

Multiply through by 3 to get whole numbers;

a = 2, b = 3, c = 1 and d = 3

2Fe + 3CuSO₄ → Fe₂(SO₄)₃ + 3Cu
