Sodium Hypochlorite is an unstable compound composed of sodium and hypochlorite ions. It is a chlorine compound often used as a disinfectant or a bleaching agent. It is stable in solution, though. It is light green and has the chemical formula NaClO (or NaOCl). It appears as colorless or slightly yellow watery liquid with an odor of household bleach. It is a strong oxidizing agent.
It is generally used dissolved in water at various concentrations. In the textile industry, it is used to bleach textiles. It is used to disinfect (kill bacteria) and as a bleach to remove stains from clothing. It is a compound that can be effectively used for water purification. It is not good for cotton because the sodium hydroxide normally contained eats away the clothing fibers. It is the main ingredient in laundry bleach. It reacts with acids to produce chlorine. It is used on a large scale for surface purification, bleaching, odor removal, and water disinfection. It is used extensively as a bleaching agent in the textile, detergents, and paper and pulp industries. In food processing, it is used to sanitize food preparation equipment, in fruit and vegetable processing, mushroom production, beef, poultry production, and fish processing.
