Achieve #5

Identify the oxidizing and reducing agents in the skeletal (unbalanced) reaction. Then, balance the reaction, including the phase (solid, liquid, etc.) of each species. The reaction takes place in basic aqueous solution.

Cl2O7(g)+H2O2(aq)⟶ClO−2(aq)+O2(g)


I keep getting Cl2O7(g)+4 H2O2(aq) +2OH- ⟶2ClO−2(aq)+4O2(g)+5H2O(l)
I balanced out 8 electrons in each equation to get to this answer.

can someone explain to me what I did wrong?

I think you forgot to put in that OH^- was aqueous. Everything else seems correct ! Here's my answer.

[Morgan Micallef 1A]

I don't know if you put that OH- was aqueous in your answer or not, but make sure to include the phases or achieve will mark it incorrect!

What was your half reaction for the Cl2O7 term? I can't get my O and H to balance.

thank you!!

I think the problem that your having is that you forgot to mention that phase of OH-.
