Magnesium Chloride
Magnesium Chloride (Product Code: SCI-585/254) is an analytical reagent grade magnesium chloride (MgCl2) used to demonstrate magnesium ion reactions and permanent water hardness in school and college chemistry laboratories. It comes in a 100 g pack with an MSDS, a practical quantity for class sets of test-tube reactions. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, which provides lab chemicals to institutions across India.

What Is Magnesium Chloride Used For?
In salt analysis practicals, magnesium is identified in the last cation group: with ammonium chloride, ammonium hydroxide and disodium hydrogen phosphate it forms a white crystalline precipitate of magnesium ammonium phosphate. Sodium hydroxide gives white magnesium hydroxide which, unlike zinc or aluminium hydroxide, does not dissolve in excess alkali, a handy contrast when teaching amphoteric hydroxides.
Water-chemistry lessons use magnesium chloride to prepare permanently hard water for soap tests and hardness titrations. The salt is strongly deliquescent: it pulls moisture from the air and can turn into a wet paste if the lid is left loose, so weigh portions quickly, reseal the pack and store it in a dry cupboard.
Supplier
Laboratory dealers and school suppliers who restock chemistry store rooms can source Magnesium Chloride from ScienceLab, the trading name of Jain Scientific Equipments Private Limited, Ambala. The company supplies reagents in the pack sizes stated on each listing, and buyers can ask for them to be quoted together with glassware. Read the ScienceLab profile for company details.
Related Laboratory Equipment
Reagents and materials for magnesium ion and water-hardness practicals:
- Ammonium Chloride — used with ammonia to buffer the magnesium phosphate test.
- Sodium Hydroxide — precipitates white magnesium hydroxide.
- Magnesium Ribbon — the metal itself, for comparing element and salt chemistry.
- Magnesium Sulfate — another magnesium salt that causes permanent hardness.
- Sodium Carbonate — washing soda, which removes permanent hardness by precipitation.

Frequently Asked Questions
Which test confirms magnesium using Magnesium Chloride?
A solution of Magnesium Chloride treated with ammonium chloride, ammonium hydroxide and disodium hydrogen phosphate gives a white crystalline precipitate of magnesium ammonium phosphate, the usual confirmatory test for magnesium in school salt analysis.
Does Magnesium Chloride cause hard water?
Yes. Magnesium Chloride dissolved in water causes permanent hardness, which does not disappear on boiling. Teachers use it to prepare hard-water samples so students can compare soap lather before and after softening with washing soda.
What pack size is Magnesium Chloride SCI-585/254?
Magnesium Chloride SCI-585/254 is supplied as a 100 g pack of analytical reagent grade salt, accompanied by an MSDS. For larger requirements, state the number of 100 g packs you need in your enquiry.
Why does Magnesium Chloride become wet in storage?
Magnesium Chloride is deliquescent, meaning it absorbs water vapour from the air until it dissolves in it. Keep the container tightly closed in a dry cupboard and weigh out portions quickly to keep the reagent free-flowing.
Is there an expiry date on Magnesium Chloride?
For Magnesium Chloride, shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted, and note it in the store-room register when the pack arrives.
Who supplies Magnesium Chloride SCI-585/254?
Magnesium Chloride SCI-585/254 is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab) of Ambala, Haryana, to schools, colleges, laboratory dealers and importers in India and international markets.
