Question

Help me please. iF anyone knows!​

Answer 1

Answer:

c) -0.34V

Explanation:

nernst Equation is given as,

E = Eo + 0.06/n * log [metal ion concentration] ...... (1)

here,

cell reaction is,

Ni++ + 2e- --> Ni (Reduction Reaction)

no. of electrons in reaction (n) = 2

Eo is given = -0.25V

Ni++ ion concentration = 0.01M

now, put those values in the Equation (1)

E = -0.25 + 0.06/2 * log[0.01]

E = -0.25-0.09

E = -0.34V
