Solution

1. MgI₂

On dissolving MgI₂ in water it dissociates into Mg⁺² and I^- ions

MgI₂ (aq) Mg⁺² (aq) + 2I^-

2. K₂CO₃

On dissolving K₂CO₃ in water it dissociates into K⁺ and CO₃^2- ions

K₂CO₃(aq) 2K⁺ (aq) + CO₃^2- (aq)

3. HClO₄

On dissolving HClO₄ in water it dissociates into H⁺ and ClO₄^- ions

HClO₄ (aq) H⁺ (aq) + ClO₄^- (aq)
