Which one of the following is NOT true for bleaching powder ?

Bleaching powder, chemically known as calcium hypochlorite [Ca(OCl)2], is primarily recognized for its strong oxidizing properties rather than reducing properties [2]. It is produced by the action of chlorine on dry slaked lime [1]. In chemical industries, it is extensively used as an oxidizing agent to facilitate various chemical reactions [2]. Its other major applications include bleaching cotton and linen in the textile industry [2], bleaching wood pulp in paper factories to remove lignin [2], and disinfecting drinking water to eliminate harmful pathogens and germs [2]. Because it acts as an oxidant by releasing nascent oxygen or chlorine, the statement that it is used as a reducing agent is scientifically incorrect [2]. Therefore, option 1 is the only false statement among the choices provided.
