Which of the following salts of same concentration will have same value of van't Hoff factor as that of K4[Fe(CN)6]?
Options
MgSO4
Na2SO4
Al2(SO4)3
Al(NO3)3
MCQ
Solution
Al2(SO4)3
Explanation:
The salts which dissociate to give same number of ions and concentrations have same van't Hoff factor for K4[Fe(CN)6] = 5
1. MgSO4 = 2 ions
2. Na2SO4 = 3 ions
3. Al2(SO4)3 = 5 ions
