Explanation of Solution

Barium nitrate dissociates to produce Ba²+ and NO₃- which are dication and monoanion respectively.

Sodium chloride dissociates to produce Na+ and Cl- which are monocation and monoanion respectively.

Potassium carbonate dissociates to produce K+ and CO₃²- which are monocation and dianion respectively.

Magnesium sulfate dissociates to produce Mg²+ and SO₄²- which are dication and dianion respectively.
