Phosphoric acid does not have this ability because it is not an oxidant. The acidity of the hydrogen halides Hydrogen chloride as an acid WebThis is because the enol is so reactive toward bromine that it never has a chance to reverse step 2, i.e., it is not protonated by hydronium ion to give back the conjugate acid of the carbonyl compound. So bromine reacts much more rapidly than does hydronium ion with the intermediate enol. Once formed, the enol always goes on to brominated product. lakes in colorado to live on

Webhypobromous acid. For these reasons bromine is effective for applications such as microbiological control in cooling towers with pH in the 7.5 to 9.0 region. pH is an important variable in bromine-water systems, since it determines what form the bromine takes.
