PLEASE HELP: methanol oxidation
« on: March 08, 2009, 04:28:29 PM »
i need help balancing the following equation:
KMnO4 + H2SO4+ CH3OH + (? H2O) :rarrow: CH2O + ?x + (products) ?
ya know what i mean for some reason i just am not getting how the KMnO4 is disasosiating and reacting for this rxn. driving me crazy PLEASE HELP

i am curious what the equation is also  for the rxn of KMnO4 and formaldehyde to formic acid

Almost every linked page contains hints for your reaction.

OK, if you want to figure it out for yourself, at least balance the elements on each side of the equation.  You know that the methanol is oxidized, so you know something is reduced.  What is the oxidizer?  becaus ethat is being reduced.  And what does it reduce to?  What does reduction mean?  You can use a dictionary if you don't care for your textbook's explanation.

This is how we help on this forum.  We give hints, to help you learn, so you do better on the exam, when they change the problem slightly.
Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.

im sorry i guess i didn't read the forum rules, guilty as charged
that is precisely the reason people don't ask enough question to quench there thirst for knowledge, because they are all afraid they will run into someone condescending and rude. i know people might think that because we are chemistry nerds we don't know how to talk to people butt come on honestly

We are not kid eaters. We are more than happy to help someone who have tried and hit the wall, unfortunately most people coming here ask questions first, try to do their leg work later (if ever).

If you will follow links from google search you will see that quite often one simple cation appears between reaction products.
