Net Ionic Equation (Tungsten 3+)
« on: June 03, 2012, 03:36:56 PM »
The oxidation of W3+ to ((WO2)2+) with permanganate in acidic medium, where Mn2+ is formed.

I cannot for the life of me get these right. I've been at it for a while. Any insight?

I'm having trouble matching the intermediates and eliminating to the net equation. Any insight as to what is the correct approach? Appreciate any help.

8 H+ + MnO4āˆ’ + 5 eāˆ’ ā†’ Mn2+ + 4 H2O would be permanganate in acidic medium --> could I just include W3+ on the reactants side and balance from their with its appropriate product?

You got the permanganate half right, now try to balance the tugnsten half reaction.
