How To Test For Hydrogen Peroxide Presence

The method of detecting hydrogen peroxide
Where there is hydrogen peroxide in the object to be tested, it should be done by an appropriate method. Take a clean test tube and inject a little of the object to be tested into it. Then put a little manganese dioxide powder into it. If there are bubbles that escape quickly, and the bubbles can make the wooden strip with fire star reignite, it is proved that the substance contains hydrogen peroxide. When hydrogen peroxide meets manganese dioxide, it will decompose and produce oxygen and water. Oxygen has the property of supporting combustion, so it can make the wooden strip with Mars reignite. This is one of the convenient and sure ways to test whether hydrogen peroxide exists. Or take a potassium iodide starch test strip, make it moist, and dip it in the object to be tested. If the test strip turns blue quickly, it is also proved that there is hydrogen peroxide. Because hydrogen peroxide can oxidize potassium iodide, iodine elemental substance, iodine is blue when it encounters starch. When performing these tests, be sure to abide by the rules and ensure safety in order to obtain certain results.
