Application
1. It is used in the printed circuit boards, in the olefin polymerization as an initiator, used for photography, as an additive for preserving the food, as an oxidising agent, to wash the infected yeast, for removing the pyrogallol stains, as a depolarizer in batteries and as a common ingredient in the hair bleaches.
2. Ammonium persulfate is used as a bleach because it is a strong oxidizing agent. It is used as a disinfectant because it is a powerful bactericide and fungicide.
