From the following information, calculate the solubility product of AgBr.
`AgBr(S)rightarrowAg ((s)) + Br^(-) ((aq)) , E^(@) = 0.07V`
` Ag^(+) ((aq)) to Ag((s))`, `E^(@) = 0.80 V`

A

`1.6xx10^(-5)`

B

`1.5xx10^(-8)`

C

`3.2xx10^(-10)`

D

` 1.5xx10^(-10)`

Text Solution

Verified by Experts

The correct Answer is:
D
For the equilibrium
`AgCl(s)overset(H_(2)O)hArrAg^(+)(aq)+Cl^(-)(aq)`
`k_(sp)=[Ag^(+)][Cl^(-)]`
`AgCl(s)+e^(-)rarrAg(s)+Cl^(-)(aq)E^(@)=0.22V`
`Ag(s)rarrAg^(+)(aq)+e^(-),E^(@)=-0.80V`
`AgCl(s)rarrAg^(+)(aq)+Cl^(-)(aq)`
`E^(@)=(0.22-0.80)V`
`=-0.58V`
