Balancing Redox equations half reaction method

Click For Summary
SUMMARY

The discussion focuses on balancing the redox equation for the reaction of hydrogen peroxide (H2O2) in an acidic solution. The correct half-reaction method involves balancing oxygen with water (H2O) and hydrogen with protons (H+). The final balanced equation is 2 e- + 2 H+ + H2O2 → 2 H2O. Participants clarify that the original poster's confusion stems from misinterpreting the requirement to balance a half-reaction versus a full reaction, which is not feasible in this context.

PREREQUISITES
  • Understanding of redox reactions
  • Knowledge of half-reaction method

Homework Statement


This is my equation. I needed to balance it in an acidic solution.

H2O2(aq)---->H2O(l)


Homework Equations


I know that you should balance oxygen using H2O & hydrogen using H+.
I am confused on how you balance the ionic charges.


The Attempt at a Solution


This is what I got for my answer
2 e- + 2H+ +H2O2---->2H2O

Not clear to me what you are doing - are you expected to balance a half reaction? If so, what you did is OK.

What you wrote suggests you are asked to balance it as a full reaction, which is impossible.
