Question

On adding AgNO3 solution to a solution of [Pt(NH3)3Cl3]Cl, the percentage of total chloride ion precipitated is:

• A. 100
• B. 75
• C. 50
• D. 25

Answer 1

Answer: (D)

25

Answer 2

[Pt(NH3)3Cl3]Cl [Pt(NH3)3Cl3]+ (aq) + Cl– (aq)

Out of four Cl– only one Cl– (i.e. 25%) present in ionization sphere will give preciptate.

Ag+ + Cl– $\longrightarrow$ AgCl ¯ (white).
