A solution is ` 0.01 M Kl and 0. 1 M KCl . `If solid ` AgNO_3 ` is added to the solution, what is the `[1^(-) ]` when `AgCl ` begins to precipitate
` [K_(sp) (Agl) =1.5 xx 10^(-16) , K_(sp) (AgCl) =1.8 xx 10^(-10)]`

A

` 3.5 xx 10^(-7)`

B

` 6.1 xx 10^(-8) `

C

` 2.2 xx 10^(-7) `

D

` 8.3 xx 10^(-8) `

Text Solution

Verified by Experts

The correct Answer is:
D
` K_(sp) =[Ag^(+) ][Cl^(-) ] `
` [Ag^(+) ] =(1.8 xx 10^(-10))/( 10^(-1) )= 1.8 xx 10^(-9) `
` [I^(-) ]=(K_(sp) )/( [Ag^(+) ]_(cl^(-) ))=(1.5 xx10^(-16))/( 1.8 xx 10^(-19)) = 8.3 xx 10 ^(-8) M`
