For chemical disinfection of water the following disinfectants can be used: - Chlorine (Cl2) - Chlorine dioxide (ClO2) - Hypo chlorite (OCl-) - Ozone (O3) - Halogens: bromine (Br2), iodene (I) - Bromine chloride (BrCl) - Metals: copper (Cu2+), silver (Ag+) - Kaliumpermanganate ...
NBS is commercially available. It can also be synthesized in the laboratory. To do so, sodium hydroxide and bromine are added to an ice-water solution of succinimide. The NBS product precipitates and can be collected by filtration. Crude NBS gives better yield in the Wohl-Ziegler reaction. In...
Bromine water is a mild oxidizing agent that converts the aldehyde functional group into a carboxylic acid. Product: The product formed is D-gluconic acid (C6H12O7), where the aldehyde group (-CHO) is converted into a carboxylic acid (-COOH). Step 3: Reaction of D-Glucose with HNO3 (...
