Bromine water: A positive test
Bromine water, an acid-base indicator used for testing the presence of various substances is called bromine water. Bromine water can be added to any solution and a color change will result. A colour change is a sign that a substance has been added to the solution. It may also indicate the presence of other compounds. The main compounds that are likely to give a positive test with bromine water include: unsaturated hydrocarbons; phenols; aldehydes; and carboxylic acids (Pandey & Rajpoot, 2016). These compounds are not the only ones that will give positive results. There may also be other substances. These include: alcohols; ketones; amines; and aromatic compounds (Nitesh & Dheeraj, 2021). When the bromine water and a mixture of acids or bases are added, it is likely that a positive test will be performed. Bromine water’s bromide ions react with the solution’s hydroxide ions, which results in colour changes. Cont….
