Bleaching Powder
Bleaching Powder (Product Code: SCL-785/137) is a chlorine-releasing calcium compound used to prepare small amounts of chlorine and to demonstrate bleaching and water disinfection in school and college chemistry laboratories. It features in the secondary-school topic on salts of everyday importance and in college available-chlorine titrations, and comes as a 500 gm pack of analytical reagent grade with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, to schools stocking chemistry lab equipment in India.

What Is Bleaching Powder Used For?
To prepare chlorine, a small amount is placed in a flask fitted with a dropping funnel and delivery tube, and dilute hydrochloric acid is added slowly inside a fume cupboard. Because chlorine is heavier than air, it is collected in gas jars by upward displacement using standard gas collection apparatus. Students then see moist blue litmus turn red and then lose its colour, and a coloured petal or cloth strip fade, which shows the bleaching action of chlorine in the presence of moisture.
For a disinfection demonstration, a pinch stirred into a large volume of water shows how chlorine compounds treat drinking-water supplies. Colleges go further and find the available chlorine by adding potassium iodide and acid, then titrating the liberated iodine with sodium thiosulphate. Bleaching powder is corrosive and loses chlorine when exposed to air and damp, so keep it tightly closed in a cool, dry place. Never store or mix it with acids or ammonia, which release harmful gases.

Frequently Asked Questions
Who supplies Bleaching Powder SCL-785/137?
Bleaching Powder (SCL-785/137) is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, Ambala, Haryana, India. The company sources this analytical reagent grade chemical for chemistry practicals and supplies it with an MSDS to institutions and dealers in India and international markets.
How much bleaching powder is in a pack?
Each pack of Bleaching Powder contains 500 gm, listed as analytical reagent grade and supplied with an MSDS. Small portions are enough for chlorine preparation and bleaching demonstrations, so reseal the pack after every use to preserve its active chlorine.
Why does bleaching powder smell of chlorine?
Bleaching Powder slowly gives off chlorine, especially in moist air, so a strong smell when the pack is opened is normal. Keep the lid closed between uses so that the active chlorine is not lost and the laboratory air stays comfortable.
What is the shelf life of Bleaching Powder?
Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Bleaching Powder loses strength sooner if left open or damp, so colleges needing an exact figure should measure available chlorine before use.
Can bleaching powder be stored next to acids?
No. Bleaching Powder must be stored away from acids and ammonia, because contact releases chlorine or other harmful gases. Keep it on a separate shelf of the chemical store, in its closed container, and label it clearly as an oxidising substance.
Is water from the bleaching powder demonstration safe to drink?
No. The Bleaching Powder disinfection demonstration shows the principle only, and real drinking-water treatment needs controlled dosing and testing. Discard the demonstration water after the lesson and explain to students how treatment plants measure the chlorine they add.
Do you ship bleaching powder in bulk or overseas?
Bleaching Powder is supplied to schools, colleges and dealers in India and international markets. As an oxidising chemical, its transport arrangements are confirmed for each order, so send the quantity and destination through our contact page.
