Question

A colourless crystalline salt, on being heated, gives a colourless gas with a pungent smell. On being passed through an $A g N O_{3}$ solution, this gas forms a white precipitate insoluble in $H N O_{3}$ but readily soluble in an $N H_{3}$ solution. Which of the following reactions can lead to the above observation ?

M g C l_{2} + H_{2} O \to M g (O H) C l + H C l
