Answer 1

Answer:

For a uni-univalent electrolyte (example : sodium chloride ,potassium chloride) the expression for ionic strength will contain only two terms i.e one for cation and other for anion. Hence, Where: m+ is the molality of cation m- is the molality of anion z+ and z- are the valencies of the cation and anion respectively. A option
