Detailed Solution

The expression to determine van't Hoff factor of a solution is given by:i=1+(n−1)αn= number of ions formed after dissociationα= Degree of dissociationwhere, i= van't Hoff factorA. For NaCl; n=2 so i=1+α B. For Ca(NO3)2; n=3 so i=1+2αC. For K4[Fe(CN)6]; n=5 so i=1+4αD. For (NH4)3PO4; n=4 so i=1+3α
