Question
The Ksp of Ag2CrO4, AgCl, AgBr and AgI are respectively, 1.1 × 10-12, 1.8 × 10-10,. 5.0 × 10-13, 8.3 × 10-17. Which one of the following salts will precipitate last if AgNO3 solution is added to the solution containing equal moles of NaCl, NaBr, NaI and Na2CrO4 ?
Options
A.AgCl
B.AgBr
C.Ag2CrO4
D.AgI
Solution
Ag2CrO4 → KSP = [Ag+]2 [CrO4-2]
⇒ [Ag+] =
= maxm
so answer is Ag2CrO4
⇒ [Ag+] =
= maxmso answer is Ag2CrO4
