Question

Does the semi-reaction given below behave as an anode or cathode when combined with a standard hydrogen electrode, what is the electrode potential?

Pt | Ti3+ (0,300M), TiO2+(0,100 M), H+ (0,200M)

TiO2+ + 2 H+ + e- ↔ Ti3+     E0= + 0,099 V

2H+ + e- ↔ H2                      E0= + 0,000 V
A. anode, - 0.012 V

B. cathode, - 0.012 V

C. anode, + 0.023 V

D. cathode, + 0.023 V
