bromsyrer

Bromsyrer, also known as hypobromous acid and its salts (hypobromites), are a group of chemical compounds containing bromine in its +1 oxidation state. Hypobromous acid (HBrO) is a weak acid that exists in equilibrium with bromite ions (BrO2-) and bromide ions (Br-). The salts, hypobromites, are typically formed by reacting bromine with a strong base. For example, sodium hypobromite (NaBrO) is formed when bromine is added to cold sodium hydroxide solution.

These compounds are known for their strong oxidizing properties. Hypobromous acid is a potent disinfectant and is used in water treatment and sanitation to kill bacteria and viruses. It is also employed as a bleaching agent. The oxidizing power of hypobromites makes them useful in various chemical synthesis reactions.

However, bromsyrer can also be unstable, particularly in acidic conditions where they can disproportionate into bromide and bromate ions. Bromates are polyatomic ions containing bromine in the +5 oxidation state and can be oxidizing agents themselves. While hypobromites are effective disinfectants, their use requires careful control due to potential side reactions and the formation of disinfection byproducts. The stability and reactivity of bromsyrer depend significantly on factors such as pH, temperature, and the presence of other chemical species.
