TO DETERMINE THE CONCENTRATION OF HYDROGEN PEROXYDE Aim: To determine the concentration and the volume strength of hydrogen peroxide in locally purchased solution using a redox titration. Introduction: Hydrogen Peroxide is a strong oxidizing agent, readily breaking down to form water and oxygen; and aqueous solution of hydrogen peroxide can be used for bleaching hair and used as an antiseptic for minor skin wounds. However, it is a highly efficient cellular poison. It is so devastating that we have an enzyme called "peroxidase" in our body that constantly removes any hydrogen peroxide that gets into our cells. In this experiment we will use a 20-volume hydrogen peroxide solution. It has to be diluted for the use. The solution will then be titrated against an acidified standard solution of potassium manganate(VII). The concentration of hydrogen peroxide in the titrated sample is then calculated, from which it is easy to calculate the concentration of...
