WebHydrogen peroxide decomposition in 1–5 mol dm KOH and 1–2 mol dm NaOH solutions is a first-order reaction with respect to undissociated hydrogen peroxide. The decomposition is catalysed by compounds of heavy metals (Fe, Cu) present as trace impurities in these solutions and is first order with respect to them. The WebHydrogen peroxide is miscible with water, so diluting the hydrogen peroxide with ordinary water is a good way to reduce the dangerous affects of the liquid. There should be adequate ventilation when working with hydrogen peroxide, and there should be easy access to an ample water supply for thorough flushing of accidental spillage on surfaces and on people.
