H202 can behave as both oxidizing and reducing agent as shown by the two half reactions below labeled R1 ad R2, which is true?
R1: O2+2H++2e- --> H2O2 E=.68V
R2: 2H+ +H2O2+2e- -->2H2O E=1.78V-->(higher reduction potential)
--> R1 demonstrates that H202 behaves as a reducing agent basic solutions
-->R2 "
-->R1 demonstrates that H2O2 behaves as an oxidizing agent in basic solution
-->R2 ''
I understand the following
In R1, oxygen's oxidation number decreases from zero to -1, hence it underwent reduction
In R2, oxygen's oxidation number decreases from -1 to -2, its again undergoing reduction
So wouldnt reaction2 illustrate that H2O2 is an oxidizing agent in a basic solution
