Question 1

Which of the following secondary valency is unknown?

Question 2

To a solution containing one mole MCl3.4NH3, on addition of excess silver nitrate solution, it was found that two moles of AgCl are precipitated. This observation suggests that the secondary valence of M in this complex is:
