The solubility product of Pb(3)(AsO(4))(...

The solubility product of `Pb_(3)(AsO_(4))_(2)` is `4.1xx10^(-36). E^(c-)` for the reaction `:`
`Pb_(3)(AsO_(4))_(2)(s)+6e^(-)hArr3Pb(s)+2AsO_(4)^(2-)`
`E_((Pb)2^(+)|Pb)^(Θ)=-0.13V`

A

`+0.478V`

B

`-0.13V`

C

`-0.478V`

D

`+0.13V`

Text Solution

Verified by Experts

The correct Answer is:
c
`E^(c-)._(AsO_(4)^(2-)|Pb_(3)(AsO_(4))^(2)|Pb)=E^(c-)._(Pb^(2+)|Pb)+(0.059)/(6)logK_(sp)`
`=-0.13+(0.059)/(6)log4.1xx10^(-36)`
`=-0.13-0.348=-0.478V`
