Aluminium Sulphate
Aluminium Sulphate (Product Code: SCL-753/121) is a water-soluble analytical reagent aluminium salt used to demonstrate water clarification, prepare potash alum and test for aluminium and sulphate ions in school and college laboratories. Chemistry and environmental science teachers rely on its 500 gm pack for coagulation demonstrations and crystallisation work, and it arrives with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a lab consumables supplier for educational institutions.

What Is Aluminium Sulphate Used For?
For a water clarification demonstration, fill two jars with the same muddy water and stir a little aluminium sulphate solution into one. Within minutes soft flocs form, trap the fine clay particles and sink, while the untreated jar stays cloudy. The activity introduces coagulation, flocculation and sedimentation as they happen at a municipal treatment plant, and it fits neatly into a water purification science kit. Remind students that clarified water has not been disinfected and must not be drunk.
In crystal-growing work, aluminium sulphate and potassium sulphate dissolved together in warm water, with a few drops of dilute sulphuric acid to stop hydrolysis, crystallise on slow cooling as potash alum. Teachers also mix its solution with sodium hydrogen carbonate to show how a foam fire extinguisher produces carbon dioxide foam. Solutions are acidic and irritate the eyes, so wear goggles and keep the solid container closed and dry.
Supplier
Jain Scientific Equipments Private Limited operates as ScienceLab from Ambala, Haryana. It supplies reagents and consumables such as this salt to schools, colleges and distributors in India and international markets, so a science department can source its chemicals and glassware through one enquiry.

Frequently Asked Questions
Who supplies Aluminium Sulphate SCL-753/121?
Aluminium Sulphate (SCL-753/121) is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, from Ambala in Haryana, India. The company sources this analytical reagent salt and sends it with an MSDS to schools, colleges and dealers across India and international markets.
How much aluminium sulphate is in each pack?
Each pack of Aluminium Sulphate holds 500 gm of the salt, listed as analytical reagent grade and supplied with an MSDS. Departments running the jar test or alum preparation with several classes can request more than one pack in the same enquiry.
Is aluminium sulphate the same as alum?
No. Aluminium sulphate is the single aluminium salt, while potash alum is a double salt of potassium sulphate and aluminium sulphate, which is why aluminium sulphate is used to prepare alum. We list Potash Alum separately for comparing the crystals.
Does the aluminium sulphate clarification demo make water safe to drink?
No. Aluminium sulphate only settles suspended particles in the classroom jar test; it does not disinfect the water. Treated demonstration water should therefore be discarded, and the lesson can go on to explain the separate disinfection step used at treatment plants.
Which hydrate form of aluminium sulphate is supplied?
The listing for Aluminium Sulphate does not state the hydrate form. If you are calculating quantities for alum preparation or a coagulant dose, confirm the form through our contact page before ordering so that your worksheet figures match the salt received.
What is the shelf life of Aluminium Sulphate?
Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Store Aluminium Sulphate tightly closed in a dry cupboard, and keep the supplied MSDS with the stock.
Can you supply aluminium sulphate to several schools or for export?
Yes. Aluminium Sulphate can be quoted for single schools, school groups and dealers in India and international markets. Include the number of packs and each delivery point in your enquiry so that one quotation covers the whole order.
