more balancing

Submitted by srosierose on 26 October 2004 - 5:13am.

my homework question is...
potassium permanganate (KMnO4) is a very powerful oxidizing agent. it is often used in analyses for iron(II) salts because it quantitatively and rapidly oxidizes Fe2+ to Fe3+. write and balance the oxidation-reduction equation for the reaction of the permanganate ion MnO4- with Fe2+ in acidic aqueous solution, producing Mn2+ ion and Fe3+ ion. i am no good at writing out these equations. please help. thanks :oops: :(

K+ MnO4- Fe2+
-> K+ Mn(2+) O(2-) O2 O- Fe2+
-> K+ Mn(2+) O(2-)2 O2 Fe3+

OR

K+ MnO4- 3(Fe2+)
-> K+ Mn(2+) O(2-) O2 O- 3Fe2+
-> K+ Mn(2+) O(2-)4 3Fe3+
