JEE Main 2021 — Ionic Equilibrium Question with Solution
From: JEE Main 2021 (Online) 20th July Evening Shift
Question
A solution is 0.1 M in Cl and 0.001 M in CrO. Solid AgNO3 is gradually added to it. Assuming that the addition does not change in volume and Ksp(AgCl) = 1.7 1010 M2 and Ksp(Ag2CrO4) = 1.9 1012 M3.

Correct answer
DAgCl will precipitate first as the amount of Ag+ needed to precipitate is low.
Step-by-step explanation
Conc. of Cl = 0.1 M = 101 M
Conc. of CrO = 0.001 M = 103 M
Ksp(AgCl) = [Ag+][Cl]
[Ag+]AgCl =
AgCl will be precipitate first
Conc. of CrO = 0.001 M = 103 M
Ksp(AgCl) = [Ag+][Cl]
[Ag+]AgCl =
AgCl will be precipitate first
