Question

Provide the correct coefficients to balance the following equation:
___ Fe(NH4)2(SO4)2·6H2O + ___ H2C2O4 + ___ K2C2O4 + ___ H2O2 -----> ___ K2Fe(C2O4)3·3H2O + ___ (NH4)2SO4 + ___ H2SO4 + ___ H2O

I'm usually okay when it comes to balancing equations but this one has me really stumped! Please help explain this to me.

Answer 1

I expect your problem is that someone made a typo. I think that K2Fe(C2O4)3 on the right should be K3Fe(C2O4)3. As it stands Fe has an oxidation state of +4 which is not all that easy to explain but K3Fe(C2O4)3 Fe is +3 and the Fe goes from +2 on th left to +3 on the right. Look into that as the main source of trouble you are having. Check the rest of it for typos, too.

Answer 2

yes, you were right there was indeed a typo! thank you for pointing it out, it makes much more sense now! :)
