Hydrobromic acid is a clear or yellowish liquid used in industry and laboratories for isomerization, polymerization, and hydration reactions. It is also used to produce inorganic bromides and can be found in medicine, disinfectants, and pesticides. It is a strong acid that can cause respiratory and skin irritation, and should be handled with safety precautions.
Hydrobromic acid is a type of clear or yellowish liquid containing hydrobromic acid and water. This acid is stable under normal conditions and often used in industry to produce isomers and polymers, as well as for hydration reactions. It is also used in laboratories for scientific experiments. Generally, hydrobromic acid is referred to as hydrogen bromide, or HBr, by those who work with it.
A hydrogen bromide molecule consists of a hydrogen atom attached to a bromine atom, both elements found on the periodic table. It generally exists as a gas but can be completely dissolved in water to create an acid, or a substance with a pH (parts of hydrogen) below seven. The stronger the acid, the more corrosive and dangerous the substance. Acids can be used to neutralize bases, or substances with a pH greater than 7. Hydrobromic acid has a melting point much lower than water, 14°F (-10°C), and its melting point boiling point is higher, 251.6°F (122°C).
Hydrobromic acid is used in isomerization, or a chemical reaction that causes the structure of molecules to change without changing their molecular composition, and in polymerization, or a reaction that connects the strands of molecules into long chains. Isomerization is especially important for substances such as fuels, evidence of which suggests they burn better with a bent molecular structure rather than a straight line. Polymerization is most common in the creation of plastics. Additionally, hydrobromic acid can be used in hydration reactions to create certain alcohols.
The main use of this acid, however, is to produce inorganic bromides. Inorganic bromides can be found in medicine, disinfectants and can be used in the petroleum industry. They are also frequently used in various pesticides. A commercial product, this acid normally comes in drums and should be stored in cool, dry places out of the sun and near nothing that could act as an oxidizing agent, causing a reaction. The liquid will darken when exposed to light.
A strong acid, hydrobromic acid has a pungent odor and can irritate the nose and lungs if inhaled and can cause burning and shortness of breath. Prolonged exposure may cause respiratory secretion. Additionally, it can cause irritation – or even burns – to the skin if touched, and prolonged exposure could cause a skin condition called dermatitis. It is poisonous if ingested. Safety goggles and gloves should always be worn when working with the substance, and good ventilation is also important, especially the use of a fume hood when working in a laboratory.
