Question

The reaction 2H2O2  2H2O + O2 has the following mechanism?

H2O2 + I–  H2O + IO–
H2O + IO–  H2 + O2 + I–
The intermediate(s) in the reaction is (are):

A) H2O B) IO– C) Both A & B D) I–

Answer 1

Look for something which is both on the left and right of the set of equations.

It is IO-.
