Question

What would be the solubility of silver chloride in `0.10M NaCI` solution?
`K_(sp) for AgCI = 1.20 xx 10^(-10)`
A. 0.1M
B. `1.2xx10^(-6)M`
C. `1.2 xx 10^(-9) M`
D. `1.2 xx 10^(-10)M`

Answer 1

Correct Answer - C
`K_(sp)=[Ag^(+)][Cl^(-)]`
or `[Ag^(+)]=K_(sp)//[Cl^(-)]`
`=(1.2 xx 10^(-9))/(1xx10^(-1))=1.2 xx 10^(-9)M`
