Answer 2

Answer:

Chlorine is produced from ordinary salt – one of the most abundant, essential minerals on earth. The chlorine production process is extraordinarily efficient: hydrogen, a byproduct of the production process, is used as an energy source in many manufacturing facilities; and sodium hydroxide, another byproduct, is a valuable and essential product used to manufacture many consumer and industrial products. Chlorine chemistry helps keep drinking water and swimming pools safe. Before cities began routinely treating drinking water with chlorine-based disinfectants, thousands died every year from waterborne diseases such as cholera, typhoid fever, dysentery and hepatitis A. Chlorine-based pool and spa disinfectants help keep recreational waters safe by destroying waterborne pathogens that can result in illnesses, such as diarrhea, swimmer’s ear or skin rashes, including athlete’s foot.
