Question

How much amount of AgCl is precipitated, when 1 mole of $[Pt {(en)}_{2} (H_{2} O) Cl] {Cl}_{3}$ Complex is treated with excess AgNO₃ ?

Moderate

A

143.5 gr
B

287 gr
C

430.5 gr
D

574 gr

Solution

$[Pt {(en)}_{2} (H_{2} O) Cl] {Cl}_{3} + \underset{}{{AgNO}_{3} (excess) \to [Pt {(en)}_{2} (H_{2} O) Cl] {({NO}_{3})}_{3}} + \underset{ppt}{3 AgC} l ↓$ ,1 mole of given complex treated with excess AgNO₃ to form 3 moles of AgCl precipitate is formed, that is 430.5 gr AgCl ppt out.
