Question

How much amount of AgCl is precipitated, when 1 mole of $[Pt {(en)}_{2} {(H_{2} O)}_{2}] {Cl}_{4}$ Complex is treated with excess AgNO₃ ?

Moderate

A

143.5 gr
B

287 gr
C

430.5 gr
D

574 gr

Solution

$[Pt {(en)}_{2} {(H_{2} O)}_{2}] {Cl}_{4} + \underset{}{{AgNO}_{3} (excess) \to [Pt {(en)}_{2} {(H_{2} O)}_{2}] {({NO}_{3})}_{4}} + \underset{ppt}{4 AgC} l ↓$ ,1 mole of given complex treated with excess AgNO₃ to form 4 mole of AgCl precipitate is formed, that is 574 gr AgCl ppt out.
