question about balancing a reaction


Recommended Posts

hi,

I was asked to balance this reaction : 

H3PO4(aq) + KMnO4(aq) + H2SO4(aq) → H3PO4(aq) + MnSO4(aq) + K2SO4(aq) + H2O(l)

can I get some help? why we cant balance this reaction? and what can we say about a reaction that has the same compound as a reagent and a product?

 

thank you

This must be homework ?

Is the reaction equation complete?

Such a compound has a special name do you know what it is  -  It begins with the letter C

Looks to me like a redox reaction that you have to balance by identifying how many electrons are transferred from what ion to what ion, and then accounting for H2O ions depending on whether you are in an acid or basic solution. This is called the ion-electron balancing method.

The acid --in this case-- or the base in others, is there to tell you that you must balance by using protons.

Bases balance by using OH- ions.

Is this homework?

The reaction can not work.
It's impossible to balance it.

The electrons won't add up.

Doh! You're right. Manganese can't take what's not there.

No it's now ancient history.

Check the OP date.

Oh, boy. I wish there were a filter for the really important questions. So much time wasted on the I'm-totally-confused user! ;)
