Interpretation :
Name of the given salts must be matched with microscopic pictures of that compound in aqueous solution.
Concept Introduction :
Salt solutions are strong electrolytes and these undergo complete dissociation in aqueous solution.

Answer to Problem 42A
‘a’ will match with ‘iv’.
‘b’ will match with ‘ii’.
‘c’ will match with iii’.
‘d’ will match with ‘i’.
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.
