💡 Solution & Explanation

Due to difference in number of ion formed, there 2will be a difference in the freezing point measurement. AgNO3 test – one mole of each complex on reaction with excess AgNO3 will give two moles and three moles of AgCl respectively. Since Co is in the same oxidation state and number of NH3 ligands differ by one only there will be no difference in magnetic moment. MnO2 test is not quantitative hence number of Cl- ions cannot be identified.
