Some chemists at wished to perpare a saturated solution of a silver compound and they wanted it to have the highest concentration of silver ion possible. Which of the following compound would they use ?
`K_(sp) (AgCI) = 1.8 xx 10^(-10), K_(sp) (AgBr) = 5.0 xx 10^(-13)`,
`K_(sp) (Ag_(2)CrO_(4)) = 2.4 xx 10^(-12) ["Use" 3sqrt(0.6) = 0.84]`

A

AgCl

B

AgBr

C

`Ag_(2)CrO_(4)`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
C
`Ag^(+)` concentration for saturated solution in water
`AgCl : sqrt(1.8xx10^(-10))`
`AgBr sqrt(5.0xx10^(-10))`
`Ag_(2)CrO_(4) : 2((2.4xx10^(-12))/4)^(1/2)`(Highest)
