Chlorine levels in pool water is dependent on the pH of the water, which can be optimized with chemicals such as hydrochloric acid. It is used in the chemical industry in the large-scale production of vinyl chloride used to make polyvinyl chloride (PVC) plastic, and it is one of the chemicals that is used to produce polyurethane foam and calcium chloride. The saltwater clearly isn't harmful, but the chlorine gas rapidly escapes from the solution and into the surrounding air, where you and anyone nearby can inhale it. Generates highly toxic chlorine gas. <<2e54990726c1a14388e029be89ea0bd1>]>> �� 8cg��L��K��%��Nov�f��ZѴ�8U��=�*�"ov"?�ڦ�V,3�Z��~�(���_T�ѨT�̛��*��fJP�A�N���.��W���CI�PF��-�`�e}����6���z㤎����C�Q�[\#I�K�gc'-81Τ Chlorine gas and water combine to make hydrochloric or hypochlorous acids. a=)o^F�F�����R��4�� v~*w@�����c��f�l���*�BхOyW��u�4�o�����t�9����JH�R;v/���x'��?� ����܅�c 5*B��-Q2�t��l3�3�:�Ω��9�����Ow�I���h�Ws[�. Hydrochloric acid is generally recognized as safe when used as a buffer and neutralizing agent. 0000022163 00000 n 0000000016 00000 n While it's common to label chemicals and store them separately in a lab, it's also good practice to do this in a home. Chronic exposure to hydrochloric acid can be dangerous. In the lab, avoid mixing chemicals near burners. 0000002845 00000 n Even in the home, it's important to have a fire extinguisher handy and work with ventilation. 0000024832 00000 n The U.S. Centers for Disease Control and Prevention (CDC) notes that hydrochloric acid can cause eye damage, even blindness, if splashed in the eyes. Print this Page. It corrodes most metals immediately … Long-term exposure to hydrochloric acid is unlikely for most consumers. 0000003090 00000 n Acids with cyanide salts or cyanide solution. Calcium chloride also has uses in food production as a stabilizer and firming agent, for example in baked goods, as well as uses as an antimicrobial. May generate an explosively unstable solid. Learn more about the chemistry in the products we rely on every day, including how and why particular chemicals are used in different products, and health and safety information about these chemicals. Produced as early as the 16th century, hydrochloric acid was historically known as spirits of salt and is sometimes called muriatic acid. Hydrochloric acid is used for: 0000008368 00000 n Plastic containers, such as those made of PVC, can typically be used to store hydrochloric acid. 0000017396 00000 n Household chemicals aren't any safer than lab chemicals. Bleach + Rubbing Alcohol = Toxic Chloroform. )x�Mb�W���*QX%�߇�&��E� ���_^�hȄ�J:�Nzs�;Q��B�E�rs�y����|d��n� 0000010636 00000 n If used in the workplace, it is recommended that an eye flush station be available in case of accidental exposure. 0000019740 00000 n The sodium hypochlorite in household bleach reacts … For example, don't store muriatic acid (hydrochloric acid) with peroxide. Hydrochloric acid is used to adjust the pH of swimming pool water. She has taught science courses at the high school, college, and graduate levels. trailer Phosphides (e.g., sodium phosphide) with water. When chlorine bleach is mixed with an acid, chlorine gas is produced. When hydrochloric acid is mixed or reacted with limestone, it produces calcium chloride, a type of salt used to de-ice roads. Avoid storing household bleach together with peroxide and acetone. 0000000836 00000 n Hydrochloric acid in its concentrated, liquid form has a strong irritating odor and is very corrosive. May form highly toxic phosphine gas. The food industry uses hydrochloric acid to process a variety of food products, such as corn syrups used in soft drinks, cookies, crackers, ketchup and cereals. Be sure to keep incompatibilities in mind when reusing containers to store other chemicals. It is used for a variety of purposes and is available at concentrations from 10 to 34 percent depending on its application. 0000002294 00000 n Hydrochloric acid is the water-based, or aqueous, solution of hydrogen chloride gas. Personal protective equipment (PPE) such as vapor respirators, rubber gloves, splash goggles and face shields should be used when handling hydrochloric acid. Food and beverages contain small amounts of hydrochloric acid that are “neutralized and buffered during ingestion and digestion, or after absorption” according to the U.S. Food and Drug Administration. Occupational exposure can occur in industrial environments by inhalation or skin contact during the production and use of hydrochloric acid. May explode upon heating. In other words, sodium hypochlorite and hydrochloric acid make saltwater and chlorine gas. Here are some examples of mixtures to avoid: While it may seem like chemistry is a good science to learn through experimentation, it's never a good idea to randomly mix together chemicals to see what you'll get. It can cause damage, such as chemical burns, upon contact, according to the U.S. National Library of Medicine. At home, avoid mixing chemicals near burners, heaters, and open flames.
