How To Measure Hydrogen Peroxide
Method for measuring hydrogen peroxide
To measure hydrogen peroxide, follow the following methods. Prepare an appropriate amount of test solution, which contains the hydrogen peroxide to be measured.
Take a certain amount of test solution and put it in a clean container. React with suitable chemical reagents. Commonly used, such as potassium iodide and hydrogen peroxide. When potassium iodide encounters hydrogen peroxide, under specific conditions, it can react to produce something that can be easily detected.
In the reaction system, add an appropriate amount of indicator. This indicator can be characterized by obvious color changes due to the reaction process or the characteristics of the product. If starch encounters iodine produced by the reaction, it can be blue, and the color change can be used to judge the degree of reaction.
Then titrate the reaction system with a standard solution of known concentration. Add the standard solution slowly and closely observe the changes in the indicator. When the color of the solution reaches a specific end point, that is, when the reaction is complete, record the volume of the standard solution consumed.
According to the metrological relationship of chemical reactions, the content of hydrogen peroxide in the test solution can be obtained after rigorous calculation. The key here is to accurately operate each step to ensure that the dosage of reagents is accurate and the reaction conditions are suitable, so as to obtain reliable measurement results.
