Equilibrium Reactions of in Water

The wet case

  1. 2 e- + 2H+  = H2

  2. 4 e- + O2  + 4H+  = 2H2O

  3. 2 e- + Fe(OH)2  + 2H+  = Fe + 2H2O

  4. 2 e- + Fe2+  = Fe

  5. 2 e- + Fe(OH)3-  + 3H+  = Fe + 3H2O

  6.  e- + Fe(OH)3  + H+  = Fe(OH)2 + H2O

  7.  e- + Fe(OH)3  + 3H+  = Fe2+ + 3H2O

  8. Fe(OH)3-  + H+  = Fe(OH)2 + H2O

  9.  e- + Fe(OH)3  = Fe(OH)3-

  10. Fe3+  + 3H2O  = Fe(OH)3 + 3H+

  11. Fe2+  + 2H2O  = Fe(OH)2 + 2H+

  12.  e- + Fe3+  = Fe2+

  13. Fe2+  + H2O  = FeOH+ + H+

  14. FeOH+  + H2O  = Fe(OH)2(sln) + H+

  15. Fe(OH)2(sln)  + H2O  = Fe(OH)3- + H+

  16. Fe3+  + H2O  = FeOH2+ + H+

  17. FeOH2+  + H2O  = Fe(OH)2+ + H+

  18. Fe(OH)2+  + H2O  = Fe(OH)3(sln) + H+

  19. FeOH2+  + H+  = Fe2+ + H2O

  20.  e- + Fe(OH)2+  + 2H+  = Fe2+ + 2H2O

  21.  e- + Fe(OH)3(sln)  + H+  = Fe(OH)2(sln) + H2O

  22.  e- + Fe(OH)3(sln)  + 2H+  = FeOH+ + 2H2O

  23.  e- + Fe(OH)3(sln)  + 3H+  = Fe2+ + 3H2O
