JEE Main 2021 (Online) 20th July Evening Shift | Ionic Equilibrium Question 76 | Chemistry

A solution is 0.1 M in Cl^$$-$$ and 0.001 M in CrO$$_4^{2 - }$$. Solid AgNO₃ is gradually added to it. Assuming that the addition does not change in volume and K_sp(AgCl) = 1.7 $$\times$$ 10^$$-$$10 M² and K_sp(Ag₂CrO₄) = 1.9 $$\times$$ 10^$$-$$12 M³.

Select correct statement from the following :

AgCl precipitates first because its K_sp is high.

Ag₂CrO₄ precipitates first as its K_sp is low.

Ag₂CrO₄ precipitates first because the amount of Ag⁺ needed is low.

AgCl will precipitate first as the amount of Ag⁺ needed to precipitate is low.
