Calculate the E and `E^(@)` of the cell
`Ni | Ni^(2+) || Cu^(2+) | Cu`
from the following half-cell reactions:
`{:(Ni^(2+) + 2e^(-) rarr Ni,,E^(@) = - 0.25 " volt"),(Cu^(2+) + 2e^(-) rarr Cu,,E^(@) = + 0.34 " volt"):}`
(Given: `[Ni^(2+)] = 1 M " and " [Cu^(2+)] = 10^(-3) M`)

Text Solution

Verified by Experts

The correct Answer is:
`E_("cell")^(@) = 0.59 " volt"; E_("cell") = 0.5015` volt
