Balance the following equation by the half-reaction method. The reaction takes place in basic solution.
Fe(OH)2(s) + O2(g) --> Fe(OH)3(s)
The Attempt at a Solution
All the other problems like this had 2 reactants and 2 products. What's confusing me about this problem is that there is only 1 product. So I'm not really sure how to set up the two half-reactions. What I tried was:
Fe(OH)2(s) --> Fe(OH)3(s)
O2(g) --> Fe(OH)3(s)
But the problem with that is that I cannot balance the second one since there is Fe on only one side. Any help would be really appreciated.
