Bromine Water Extra Pure
Original price was: $ 19.00.$ 18.00Current price is: $ 18.00.
Bromine Water Extra Pure is a highly purified aqueous solution of bromine, commonly used in laboratory settings for qualitative analysis, halogenation reactions, and redox studies. It acts as a powerful oxidizing and electrophilic brominating agent, making it ideal for detecting unsaturation in organic compounds—such as alkenes and alkynes—through decolorization tests. In inorganic chemistry, it is utilized for oxidation of specific ions and elements in solution. The extra pure grade ensures low contamination and consistent bromine concentration, crucial for reproducible analytical results. It should be stored in amber, airtight containers in a cool, well-ventilated area, and handled with proper protective equipment due to its corrosive and volatile nature.

- Phenol and Aromatic Compound Testing
- Used to detect phenols and other electron-rich aromatic compounds through bromination reactions that form white precipitates (e.g., 2,4,6-tribromophenol).
- Mild Oxidizing Agent in Redox Reactions
- Acts as a moderate oxidizer for studying redox behavior in inorganic and general chemistry labs.
Secondary Uses
- Demonstrating Halogen Reactivity
- Common in teaching labs to demonstrate halogen displacement reactions and reactivity trends across Group 17 elements.
- Colorimetry and Reaction Rate Studies
- Used in kinetic experiments to observe rate of decolorization with different substances—excellent for reaction rate studies in physical chemistry.
- Preparation of Brominated Derivatives
- Sometimes used as a reagent source of Br₂ in gentle bromination reactions or derivative formation for structure elucidation.
