Status of Hydrogen Peroxide Solution 10 V in Commercialized Samples

Abstract

Hydrogen peroxide (H 2 O 2) is one of the most powerful oxidants used in many sectors. Analytical method such as titration by permanganometry is used to maintain the quality of products containing H 2 O 2. Thus, the objective of this work was to evaluate commercial samples of H 2 O 2 10 V by permanganometry. A difference of almost 3 volumes was found in the analysis of the samples. These results can be real or assigned to the potassium permanganate solution, not automation of the results and/or instability of the H 2 O 2 solutions, for example. The main issue is, in addition to alerting the consumers to adequate storage of H 2 O 2 solutions, to alert the scientific community to the need for concomitant analysis methods for unstable products such as H 2 O 2 10 V solutions in order to avoid doubts on the results and make the manufacturers aware of these quality tests.
