Webb1 feb. 2024 · 2. Hydrogen peroxide is more unstable. Hydrogen peroxide dissipates faster than chlorine or bromine, so it's much harder to maintain it at a stable level. You would need to maintain a level of around 100ppm H202 in a spa, but it's not uncommon for this to drop to zero in just a couple of days, at which point bacteria can take over your hot tub. WebbFor toxicology and ecotoxicology assessments, concentrations or amounts of hydrogen peroxide always refer to pure (100%) hydrogen peroxide unless stated otherwise. The assessment covers risks from use of biocidal products containing hydrogen peroxide up to 49.9 %. Pure hydrogen peroxide does not exist commercially.
WebbThis extra oxygen atom is described as a “peroxidic oxygen” and is otherwise known as “active oxygen.”. Hydrogen peroxide has the ability to oxidize some compounds directly; for instance, alkenes, as shown below. The peroxidic oxygen adds to the double bond, producing a hydroperoxide, as shown in equation 7-19. WebbThis extra oxygen atom is described as a “peroxidic oxygen” and is otherwise known as “active oxygen.”. Hydrogen peroxide has the ability to oxidize some compounds directly; …
