The K(sp)" ,of "Ag2CrO4, AgCl, AgBr and ...

The `K_(sp)" ,of "Ag_2CrO_4, AgCl,` AgBr and Agl are respectively, `1.1 xx 10^(-12), 1.8 xx 10^(-10), 5.0 xx 10^(-13), 8.3 xx 10^(-17)`. Which one of the following salts will precipitate last if `AgNO_3` solution is added to the solution containing equal moles of NaCl, NaBr, Nal and `Na_2CrO_4?`

A

AgBr

B

`Ag_(2)CrO_4`

C

AgI

D

AgCl

Text Solution

Verified by Experts

The correct Answer is:
