Web11 sep. 2024 · How quickly does h2o2 evaporate? 5 shows that the relative decomposition of hydrogen peroxide during evaporation decreases with increasing temperature. At 130 °C the relative decomposition is only about 10%, i.e. from 33 g hydrogen peroxide evaporated per 1 h about 3.3 g hydrogen peroxide are decomposed per 1 h. Web5 okt. 2024 · Hydrogen Peroxide: Hydrogen peroxide's chemical representation is h2o2. It has uses in industry in it's purest form but the product available to most of us over-the-counter is usually only 3% hydrogen peroxide and 97% water. It breaks down quickly when exposed to light so it generally comes in brown bottles that filter out the sun's rays.
