What brand of bleach has chlorine in it anymore?
OK, so it is sodium hypochlorite (NaOCl), which is a solution made from reacting chlorine with a sodium hydroxide solution. These two reactants are the major co-products from most chlor-alkali cells. Sodium hypochlorite, commonly referred to as bleach, has a variety of uses and is an excellent disinfectant/antimicrobial agent.
