Calculate the electrode potential of copper, if the concentration of `CuSO_(4)` is 0.206 M at `23.1^(@)` C. Given that `E_(cu^(2+)//Cu)^(@) = +0.34 V`.

A

0.50 V

B

0.41V

C

0.32 V

D

0.28 V

Text Solution

Verified by Experts

The correct Answer is:
B
Given that `[CusO_(4)]=0.26 T=296 k`
According to nernst eqauation `E_((cu)^(2+)//Cu)-(2.30 RT)/(nF)log (1)/[(Cu^(2+))]`
`=0.34 -(2.303 xx8..314 xx296.1)/(2xx96500)xxlog (1)/(0.206)=0.206 =0.32 V`
