Analysis of Hydrogen Peroxide Lab Report
Purpose
The purpose of the lab was to find the percent composition of a common bottle of
hydrogen peroxide going through an oxidation-reduction titration with potassium permanganate.
Procedure
Standardizing Potassium Permanganate Solution
Place 80 mL of potassium permanganate solution in a 100-mL beaker. This will be the
titrant. Configure a clean 50-mL buret on a support stand. The buret should be rinsed with
distilled water, then with the potassium permanganate. Once rinsed, close the stopcock and fill
the buret with the permanganate solution past the zero mark. Open the stopcock until the
meniscus is just below the 0-mL mark. An empty beaker should be placed under the buret to
catch waste. Record the starting volume.
Measure 4.0-5.0 g of ferrous ammonium sulfate, recording the precise mass. Place 10 mL
of H2SO4 and 10 mL of distilled water in a 250-mL Erlenmeyer flask, then swirl the flask to mis
the solution. Add the ferrous ammonium sulfate and swirl until dissolved.
