Sistema Cu-H20

- Cu(OH)3(s) + e- + H+ = Cu(OH)2(s) + H2O

- Cu(OH)2(s) + 2H+ = Cu+2 + 2H2O- Cu(OH)3(s) + 3H+ + e- = Cu+2 + 3H2O- Cu+3 + e- = Cu+2

- Cu(OH)3(s) + 3H+ = Cu+3 + 3H2O

 

Sistema S-H2O

- H2S = HS- + H+

- HS- = S-2 + H+- HSO4- = SO4-2 + H+- HSO4- + 9H+ + 8e- = H2S + 4H2O- SO4-2 + 10H+ ´8e- = H2S + 4H2O

- SO4-2 + 9H+ + 8e- = HS- + 4H2O- SO4-2 + 8H+ + 8e- = S-2 + 4H2O- S(s) + 2H+ + 2e- = H2S

- S(s) + H+ + 2e- = HS-- S(s) + 4H2O = SO4-2 + 8H+ + 6e-- S(s) + 4H2O = HSO4- + 7H+ + 6e-
