For the neutralization process: an acid acts as a donor and donates protons to the base. On the other hand, the base acts as an acceptor and accepts the transferred protons. In a nutshell, neutralization is mainly proton transfer process.

As for the redox process: the oxidized material usually transfers electrons to the reduced material. In a nutshell, redox is mainly electron transfer process.

A 1.00 g sample of a hydrogen peroxide (H2O2) solution is placed in an Erlenmeyer flask and diluted with 20 mL of 1 M aqueous su

Minchanka [31]

Following reaction is involved in present system:

2KMnO4 + 5H2O2 + 3H2SO4 → 2MnSO4 + K2SO4 + 5O2 + 8H2O

From the above balance reaction, it can be seen that 2 moles of KMnO4 is consumed for every 5 moles of H2O2.

Now, percent by mass of hydrogen peroxide in the original solution can be estimated as follows:
percent by mass = $\frac{\text{mass of H2O2(g)}}{\text(volume of H2SO4(ml))}X 100$
∴percent by mass = $\frac{\text{1}}{\text(25)}X 100$
= 4 %
