hi, everyone, could anyone just balance this redox equation by writing half equations for the oxidation and reduction equations and then combine the half equations and simplify if possible. Smile and also please show all working!!

The following represent redox reactions in alkaline/basic solution, but are unbalanced.

Fe(OH)2 (s) + H2O2 (aq) -> Fe(OH)3 (s)

ive tried it many times, for some reason i have the oxidation reaction... (i think)
Fe(OH)2 (s) + OH- (aq) --> Fe(OH)3 (s) +e-
however... i can not get the reduction half because i keep getting the e- also on the right hand side of the equation and they dont cancel. Maybe i got oxidation reaction wrong but i am not sure. So a detailed working out would really help. thanks!

Thank you very much, my 1st time on this forum as well.

hey usagi

In alkaline solution, hydrogen peroxide is acting as an oxidizing agent, therefore it gets reduce to OH-.

yeah i know that... but i was wondering if anyone can post a full working out. half equations and etc. thanks for your help though

hey usagi,

You got your oxidation half equation right, but isn't it pretty obvious for the other?

Fe(OH)₂ (s) + OH^- (aq) --> Fe(OH)₃ (s) +e^-     x2
H₂O₂ + 2e^- ----> 2OH^-
Overall: 2Fe(OH)₂ + H₂O₂ ----> 2Fe(OH)₃

Smile and also please show all working!!

SURE!! 
lol just joking

Astrokel has done it right
