I need help balancing these two half-reactions.
Posted: Thu Apr 14, 2016 5:44 pm
I am supposed to give the two half reactions , then the net equation, for the following redox reaction:
H2O2 + I- ----> I2 + H2O
I had balanced these as:
2 I2 + 2 electrons ----> 2 I-
H2O2 ----> H2O + 2 electrons
For a net reaction of:
H2O2 + 2 I2 ----> H2O + 2 I-
I'm told this is wrong, but I can't see any other way to do it, and don't understand what I'm doing incorrectly. Please help!
