HW 7-8: Question 3

[Shaniya Kerns 4D]

Can anyone help me figure out what i'm doing wrong?
For a particular redox reaction, ClO2^2, is oxidized to ClO4^-, and Cu2+ is reduced to Cu+. Complete and balance the equation for this reaction in basic solution. The phases are optional.
balanced reaction:
ClO2^- + Cu^2+ + 2H2O → ClO4^- + Cu^+ + 4H^+

Hi,

So I solved this question by

1) Finding the half reactions. We can also balance them like an acidic solution, and then add the OH- later.
2) We then combine these equations, but first we must make sure that the electron e- numbers are the same, so that they cancel.
3) then we add OH- by the same amount there is H+ to make water.
4) Then we simplify by cancelling out any like terms, combine and that is your reaction.

I didn't have the same question as you but I truly hope this helps, these were the exact steps I followed to find my answer!
