$ 17.00 Original price was: $ 17.00.$ 16.89Current price is: $ 16.89.
Bleaching Powder Extra Pure is a high-purity, white to slightly yellowish powder composed primarily of calcium hypochlorite, widely used in laboratory settings for disinfection, oxidation, and chemical analysis. It serves as a strong oxidizing agent and is employed in qualitative tests for halogens, water treatment simulations, and preparation of chlorine-based reagents. In microbiology and environmental science labs, it is often used to sterilize surfaces and decontaminate samples. The extra pure grade ensures high available chlorine content and minimal impurities, making it reliable for precision applications. It should be stored in a cool, dry place, in airtight containers, away from moisture, organic substances, and acids to maintain its stability and reactivity.
Bleaching Powder Extra Pure
Primary Uses
- Chlorine Source in Analytical Chemistry
- Used as a source of active chlorine in redox titrations (e.g., iodometry), and for quantifying chlorine content in qualitative or quantitative studies.
- Disinfection Studies and Microbiology Labs
- Applied in sterilization of lab surfaces, instruments, and culture containers, particularly in microbiology or biotech labs.
- Preparation of Disinfectant Solutions
- Used to prepare standard hypochlorite solutions for testing disinfectant potency and for chlorine demand experiments in water analysis.
- Oxidizing Agent in Synthesis
- Functions as a moderate oxidizer in controlled laboratory syntheses involving chlorination, oxidative degradation, or bleaching mechanisms.
Secondary Uses
- Demonstration of Redox Reactions
- Used in educational labs to visually demonstrate oxidation-reduction principles, often in color change or effervescence reactions.
- Water Treatment Simulation
- In environmental chemistry labs, used in simulated water treatment experiments to study chlorine decay and residual disinfectant levels.
- Study of Decomposition Kinetics
- Serves in experiments investigating thermal and chemical degradation of calcium hypochlorite under various conditions.
- Stain Removal Testing
- Occasionally used in textile or surface chemistry experiments to demonstrate mechanisms of stain breakdown or dye fading.
