Question

Write the molecular formulae of any 2 compounds that can be formed by the

Answer 1

Explanation:

The ions are;

Al3+  Na+ Cl- (SO₄)₃²⁻

The Cations (Positive ions) are;

Al³⁺  Na⁺

The Anions (Negative ions) are;

Cl⁻ (SO₄)₃²⁻

Compounds are formed when cations are bonded to anions

NaCl -  Formed by  Na⁺ and Cl⁻

Al₂(SO₄)₃ - Formed by Al³⁺ and (SO₄)₃²⁻

AlCl₃ - Formed by Al³⁺ and Cl⁻
