Bleaching and disinfecting agent.

The source of available chlorine in liquid chlorine bleach, which is a 5% solution of sodium hypochlorite in water. Also found in mildew removers, disinfecting cleaners, and toilet bowl cleaners. Its bleaching action arises from its ability to oxidize (chemically remove) stains. Household bleach is not systemically toxic or corrosive, but is a strong skin, eye, and respiratory irritant. Ingestion has proved serious or fatal in a few cases, but is not usually so. Sodium hypochlorite is chemically reactive, forming hazardous vapors if mixed with any products containing ammonia or with any acids. Although most of the hypochlorite breaks down into harmless compounds, a few percent of the material combines with chemicals in soil and wastewater to form chlorinated compounds such as chloroform and carbon tetrachloride that are toxic or persistent.*Corrosive. Eye, skin, and respiratory irritant. Sensitizer. Can be fatal if swallowed. Especially hazardous to people with heart conditions or asthma. Used in a wide range of household cleaners.

liquid solution of chlorine. Typically 10-15% available chlorine. High pH material. Regular additions will require applications of acid, in order to maintain the proper pH.

Bleach, a source of chlorine, with decontamination and disinfectant properties.

an unstable salt (NaOCl) used as a bleaching agent and disinfectant

Liquid chlorine with 10%-12% available chlorine and a pH of 13, requires small amount of acid to neutralize the high pH. Used for regular and superchorination, not used in spas. Has no stabilizer to protect from ultraviolet light breakdown unless stabilizer is already present in the water.

NaClO, chlorine bleach.

Liquid chlorine, hypochlorite solution, chemical formula NaOCl; usually provides 10-12% available chlorine (or about 1 lb. of pure chlorine per gallon); has a pH of 13 and requires that small amounts of acid be added to the pool to neutralize the high pH. Good for regular chlorination and superchlorination. Not recommended for spas. Does not contain conditioner or stabilizer to protect it from sunlight but it is protected if stabilizer or conditioner is already in the water.

Liquid chlorine used in pools, identical yet stronger than Clorox bleach.

Oxidizing chemical. Solution used to wash away SR-51 and SR51 spillage

Otherwise known as common household bleach, this is the most common form of liquid chlorine used in pools and spas.

Liquid chlorine for use in pools. It usually provides 12% to 15% available chlorine and has a pH of 13. It is generally cheap, but difficult and dangerous to handle. It also loses its potency rapidly and is usually only used in large commercial pools.

Good for regular chlorination and superchlorination. It is not recommended for spas and does not contain conditioner or stabilizer to protect it from sunlight, but it is protected if stabilizer or conditioner is already in the water. It usually provides 10-percent to 12-percent available chlorine (or about 1 pound of pure chlorine per gallon); has a pH of 13; and requires that small amounts of acid be added to the pool to neutralize the high pH.

Liquid bleach; used as a source of chlorine in water treatment. Laundry bleach available from grocery stores is 5.25 percent chlorine and commercial strength bleach available from swimming pool suppliers or chemical companies is usually 12.5 percent chlorine.

Sodium hypochlorite is a chemical compound with the formula NaOCl. A solution of sodium hypochlorite is frequently used as a disinfectant and as a bleaching agent; indeed, often it is simply called "bleach", though other chemicals are sometimes given that name as well.
