Hypochloric acid

Oxidation. There are 10 types of oxidative reactions in use industriaHy (80). Safe reactions depend on limiting the concentration of oxidi2ing agents or oxidants, or on low temperature. The foUowing should be used with extreme caution salts of permanganic acid hypochlorous acid and salts sodium... [Pg.97]

Hypochlorous Acid. Hypochlorous acid [7790-92-3] solutions are made for immediate use as chemical intermediates from chlorine monoxide or in bleaching and water disinfection by adjusting the pH of hypochlorite solutions. Salt-free hypochlorous acid solutions have been economically made... [Pg.143]

Chlorine gas is added to the water in some large commercial swimming pools to kill bacteria. However, in most home swimming pools, either solid calcium hypochlorite (Ca(OCl)2) or an aqueous solution of sodium hypochlorite (NaOCl) is used to treat the water. Both compounds dissociate in water to form the weak acid hypochlorous acid (HOC1). Hypochlorous acid is a highly effective bactericide. By contrast, the hypochlorite ion (OC1-) is not a very effective bactericide. Use the information above to answer the following questions about the acid-base reactions that take place in swimming pools. [Pg.19]

When a hypochlorite is treated with hydrochloric acid, hypochlorous acid is formed from the hypochlorite. It was shown in Experiment 22 / that the reaction between water and chlorine to form hydrochloric acid and hypochlorous acid was... [Pg.63]

Anions of weak acids make up the second general category of weak bases. In an aqueous solution of sodium hypochlorite (NaClO), for example, NaQO dissociates to Na and CIO ions. The Na ion is always a spectator ion in acid-base reactions. otsr (Section 4.3) The CIO ion, however, is the conjugate base of a weak acid, hypochlorous acid. Consequently, the CIO ion acts as a weak base in water ... [Pg.678]

Chloride-free solutions that contain up to 50% hypochlorous acid have sufficient stability at O C to be sold for industrial use. However, chloride reacts with hypochlorous acid to form chlorine. Thus, hypochlorous acid solutions made by chlorinating water and an alkaline compound are not stable enough to be sold. But, they may be prepared on-site by adding enough chlorine to reduce the pH to convert hypochlorite to hypochlorous acid. Hypochlorous acid may then be extracted into an organic solvent. Since hypochlorous acid is volatile, it can also be separated from the chlorination mixture as a gas and then condensed or adsorbed in water to make a chloride-free solution. [Pg.452]

In another process, acid is added to reduce the pH of a sodium hypochlorite solution to less than 5.5. The solution is sprayed into a stream of inert gas to make fine droplets or distilled. The vapor stream is adsorbed into water to make a hypochlorous acid solution with low salt. Solutions of hypochlorous acid or sodium hypochlorite can also be stripped in a column against a current of chlorine, steam, and air at 95-100°C. The exit gases are condensed to form hypochlorous acid solutions that are free of chloride. Similarly, a hydroxide solution is circulated downward through a stripping column against a stream of chlorine and an inert gas above 60°C. The effluent gas is condensed to form a salt-free solution of hypochlorous acid. Hypochlorous acid can also be made... [Pg.452]

Substitution reactions may serve an antioxidant function. Halogenation and nitration of isoflavones is discussed later in this volume. These reactions imply that the proinflamitory oxidants (hypobromous acid, hypochlorous acid, and peroxynitrite) might be reduced or moderated by reaction with isoflavones in vivo. [Pg.6]

From numerous chlorine oxides, only chlorine dioxide, CIO2, is fairly stable under certain conditions. The chlorine oxygen acids (hypochlorous acid, chlorous acid, chloric acid and perchloric acid) are formed by reaction of the corresponding chlorine oxides with water. [Pg.171]

Although a weak acid, hypochloric acid attacks aluminium because it decomposes readily into hydrochloric acid. [Pg.400]
