Question

What is the balanced equation when lead sulphate + ammonium hydroxide gives ammonium sulphate + lead hydroxide?

Answer 1

Lead sulphate - PbSO4
Ammonium hydroxide - NH3OH

Pb2SO4 + 3NH3OH = (NH3)3SO4 + Pb2(OH)3

Answer 2

Explanation:

A balanced equation is the equation in which number of reactants equal the number of products.

The reaction between lead sulphate and ammonium hydroxide is as follows.

    $PbSO_{4} + NH_{4}OH \rightarrow (NH_{4})_{2}SO_{4} + Pb(OH)_{2}$

The number of reactant species are as follows.

• Pb = 1
• $SO_{4}$ = 1

• $NH_{4}$ = 1
• OH = 1

The number of product species are as follows.

• Pb = 1
• $SO_{4}$ = 1

• $NH_{4}$ = 2
• OH = 2

Since $NH_{4}$ and OH molecules on the product side are 2, thus multiply $NH_{4}OH$ by 2. Thus, the equation will be as follows.

$PbSO_{4} + 2NH_{4}OH \rightarrow (NH_{4})_{2}SO_{4} + Pb(OH)_{2}$

Therefore, the equation is balanced.
