2. NH₄(SO₄)
3. (NH₄)₂SO₄
4. NH₄(SO₂)₃

Answer 1

Correct Answer - Option 3 : (NH₄)₂SO₄

The correct answer is (NH4)2SO4.

• The chemical formula of ammonium sulphate is (NH₄)₂SO₄.

• Ammonium sulphate is used in so many ways:-
  • It is used as an inorganic salt.
  • It is used as a soil fertiliser.
• 21% and 24% sulphur is contained by it.
• For alkaline soil, it is used as a fertiliser.
• Ammonium sulphate lowers the pH balance of the soil.
• A small amount of acid is formed by it when it is released into the soil.

• The other uses of ammonium sulphate are:-
  • herbicides, insecticides and fungicides.
