In the reaction 2 H2O2(l) --> 2 H2O(l) + O2(g) oxygen is
a) both oxidized and reduced
b) only reduced
c) only oxidized
d) neither oxidized nor reduced
Why is the answer the answer? Explain who loses and gains electrons.
Homework Answers
Oxidation state of O in H2O2 is -1
Oxidation state of O in H2O is -2
Oxidation state of O in O2 is 0
So, oxidation state of O is changing from -1 to -2 which shows
it is reduced. O is losing electron here.
Oxidation state of O is changing from -1 to 0 which shows it is
also oxidised. O is gaining electron here
