Elektrolisis larutan M(NO3)3
Katoda: M3+ + 3e- -> M..........................x4
Anoda: 2H2O → O2 + 4H+ + 4e-.............x3
-------------------------------------------------------- +
4M3 + 6H2O --> 4M+ 3O2 + 12H+
Mol H+ = mol OH-
= 0,1 x 50/1000 = 0,005
Mol unsur M = 1/3 x 0,005
Ar M= 0,17 / (1/3 x 0,005) = 102
