Vedclass · Answer

(B) The van't Hoff factor '$i$' is defined as the ratio of the normal molar mass to the observed molar mass. For electrolytes,dissociation occurs in the solution,which increases the number of particles. Since the observed molar mass is inversely proportional to the number of particles,the observed molar mass becomes less than the calculated (normal) molar mass. Consequently,for dissociation,the value of '$i$' is always greater than $1$.

The observed molar mass of an electrolyte is always less than its calculated value because the value of the van't Hoff factor '$i$' is...
