Description
Bromine water is a dilute aqueous solution of bromine (Br2). It is commonly used as a reagent in chemical reactions, particularly in organic chemistry. Bromine water is typically prepared by dissolving bromine gas in water, resulting in a yellow-orange solution. It is primarily used as a test reagent for the presence of unsaturation (double or triple bonds) in organic compounds. Bromine water reacts with alkenes and alkynes, turning from yellow-orange to colorless as the bromine is added across the double or triple bond. This reaction is used to confirm the presence of unsaturation in organic molecules.
