Q. The chemical formula of aluminum sulfate is:

एल्युमीनियम सल्फेट का रासायनिक सूत्र है:

A
Al₂(SO₄)₃
B
Al(SO₄)₃
अल(SO₄)₃
C
Al₂SO₄
D
Al(SO₄)₂
अल(SO₄)₂

Explanation

To determine the formula:

  • Aluminum ion: Al³⁺ (charge +3)
  • Sulfate ion: SO₄²⁻ (charge -2)

To balance charges:

  • Need 2 Al³⁺ ions = +6 charge
  • Need 3 SO₄²⁻ ions = -6 charge
  • Total charge = 0

Therefore: Al₂(SO₄)₃
