Ionic Equilibrium question

2021 · 20 Jul · Shift 2 · Q4

JEE MainChemistryIonic EquilibriumMCQ+4 / −1
A solution is 0.1 M in Cl −-− and 0.001 M in CrO 42−_4^{2 - }42−​. Solid AgNO3AgNO_3AgNO3​ is gradually added to it. Assuming that the addition does not change in volume and Ksp(AgClAgClAgCl) = 1.7 ×\times× 10 −-− 10 M2 and Ksp(Ag2CrO4Ag_2CrO_4Ag2​CrO4​) = 1.9 ×\times× 10 −-− 12 M3. Select correct statement from the following :
  1. A
    AgCl precipitates first because its Ksp is high.
  2. B
    Ag2CrO4Ag_2CrO_4Ag2​CrO4​ precipitates first as its Ksp is low.
  3. C
    Ag2CrO4Ag_2CrO_4Ag2​CrO4​ precipitates first because the amount of Ag+Ag^+Ag+ needed is low.
  4. D
    AgClAgClAgCl will precipitate first as the amount of Ag+Ag^+Ag+ needed to precipitate is low.
