A solution is 0.1M in Cl- and 0.001M in CrO42-.
Solid AgNO3 is gradually added to it Assuming that the addition does not change in volume and Ksp(AgCl)=1.7×10-10M2 and
KspAg2CrO4=1.9×10-12M3.

Select correct statement from the following:

Options:

Answer:
D
Solution:

i Ag+ required to ppt AgCls

Ksp=IP=Ag+Cl-=1.7×10-10

Ag+=1.7×10-9

ii Ag+ required to ppt Ag2CrO4s

Ksp=IP=[Ag+]2CrO4-2=1.9×10-12

Ag+=4.3×10-5

Ag+ required to ppt AgCl is low so AgCl will ppt 1st.
