half-life (t 1/2). It is the time required to reduce the original initator content of a solution by 50%, at a given temperature. Assuming first order decomposition kinetics, which is true for most free radical organic initiators, the half-life (t 1/2) is related to the initiator decomposition rate (k d) as follows: t 1/2 = ln2/k d
Hydrogen peroxide is a chemical compound with the formula H 2 O 2. In its pure form, it is a very pale blue, clear liquid, slightly more viscous than water. Hydrogen peroxide is the simplest peroxide (a compound with an oxygen–oxygen single bond). It is used as an oxidizer, bleaching agent, and antiseptic.
hydrogen peroxide samples are described next. Results Hydrogen peroxide is a thermodynamically unstable molecule. The rate of its decay is impacted by the solution concentration, the storage temperature, and the solution pH. A hydrogen peroxide solution that is dilute, stored at cool temperatures and acidic conditions is the most stable.
