(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The redox reaction below occurs in basic solution. Balance it with the smallest whole number coefficients and determine the coefficient for OH-.

H2CO(g) + Ag+(aq) ---> HCOOH(aq) + Ag(s).

2. Relevant equations

3. The attempt at a solution

I got the oxidation numbers and found that Ag is reduced and the H2CO is oxidized, but I cant balance the half reactions, this is what I came up with:

Ag+ + 1e- ---> Ag

H2CO + H2O ---> 2HCOOH + 1e- + H2O

Any help?
