Answer 1

Answer:

.

Given the standard potentials (E) of the following half

reactions :

Half reaction

E°

M →

(i)

+0.80V

(ii) MM3+ + 3e

+0.70V

(iii) M3+ + H2O → MO2+ + 2H+ + +0.30V

(iv) M2+ + 2H20→ MOŽ +4H+ +3e 0.20V

Calculate the standard potential of the half reaction in

which M2+ is oxidized to MO2+.
