Using data from the reduction potential table below and the reaction 2 Ag(s) + Pt2+(aq) → Pt(s) + 2 Ag+(aq) E° = 0.38 V, calculate the standard reduction potential of the half-reaction Pt2+(aq) + 2 e- → Pt(s).
Half Reaction | E° (volts)
Br2 + 2 e- → 2 Br- | 1.09
Ag+ + e- → Ag | 0.799
2 H+ + 2 e- → H2 | 0.00
