Acidic MnO4- solution reacts with ethanol, CH3CH2OH, to produce acetic acid.
« on: March 14, 2009, 10:57:16 PM »
Acidic MnO4- solution reacts with ethanol, CH3CH2OH, to produce acetic acid, CH3COOH.
I have to write a balanced equation, and this is what I have figured out thus far. 
I am having a real issue sometimes with balancing, so would someone people review my work, and tell me if I am correct? 

CH3CH2OH + MnO4- ----------> CH3CHOOH + MnO2 + OH-

In reviewing I can see that all the C, H, Mn, O are balanced on both sides. 
However what about the charges?
do both sides simply have a -1 charge?  Is it therefore equal or do I have to get each side to 0?

I am so grateful for your help.

It is completely and nicely balanced as written, but it is wrong. Check acetic acid formula.

I reckon the correct equation is,
CH3CH2OH + MnO4- ----------> CH3COOH + MnO2 + H2O
Balanced and seems correct. Is it?

Charges are not balanced, you have -1 on the left and 0 on the right.

Where is the "acidic MnO4-"?

Yea, forgot that  :(
So how do I balance the charges in this equation. Pretty elementary but I don't think its MnO3-?

Cant we balance this as a redox reaction? And doesnt MnO4- go to Mn2+, not MnO2?

I think the product of Mn7+ is up to the medium, if the medium(or catalysis) is acid, the product must be Mn2+, with the OH- medium, the product is MnO42-, and with the H2O medium is MnO2 !

oh ok...then I guess it should be balanced in basic medium...adding OH- to balance oxygen and adding H2O to balance hydrogen..

If the solution is acidic, why do you want to balance it as basic?

oops...I read the topic only now.. :D..I read this and decided it was basic medium because of the OH-...its pretty contradictory, you cant blame me for being a bit confused  ;)
