Potentiated hydrogen peroxide
Web20 Jul 2024 · Hydrogen peroxide, a versatile and readily available chemical, is a common ingredient in many disinfectant and cleaning products, due to its properties as a powerful … WebThe decomposition is characterized by the stoichiometric reaction 1. 2I − + 2H + + H2O2 → I2 + 2H2O. If the solution is relatively acidic (with a pH is less than about 3) the rate of reaction 1 is independent of the pH. Assume that the rate of the reaction under acidic conditions is given by Equation 2.
