Which of the following is the strongest oxidizing agent in acidic solution?
DATA:

Ba2+(aq) + 2 e¯ ---> Ba(s); Eo = - 2.91 V

Mn2+(aq) + 2 e¯ ---> Mn(s); Eo = - 1.18 V

2 H+(aq) + 2 e¯ ---> H2(g); Eo = 0.00 V

Au3+(aq) + 3 e¯ ---> Au(s); Eo = + 1.50 V

MnO2(s) + 4 H+(aq) + 2 e¯ ---> Mn2+(aq) + 2 H2O(l); Eo = + 1.23 V

  1. Wouldn't that be the one with the greatest tendency to gain electrons? And wouldn't that be the one with the largest reduction potential (most positive)?
