Homework Statement
HIO3 + FeI2 + HCl ==> FeCl3 + ICl + HOH
Homework Equations
Directions say it's in an aqueous solution, and HCl is a reactant, so you can add H2O and H+ to balance, right?
The Attempt at a Solution
I first found all the oxidation states:
HIO3
H = +1
I = +5
O = -2
FeI2
Fe = +2
I = -1
HCl
H = +1
Cl = -1
FeCl3
Fe = +3 (oxidation)
Cl = -1
ICl
I = +1 (reduction)
Cl = -1
HOH
H = +1
O = -2
Then tried writing/balancing the half reactions.
FeI2 ==> FeCl3 + e-
But I'm kind of stuck here, can I use HCl to balance? How else do I balance that Cl? And what about the I?
