About This Product
Magnesium chloride is used to prepare solutions for chemistry practicals and in analysis methods that specify it. It is also used when teaching inorganic salts, hydrates and deliquescence. The hydrate form on the label determines the molecular weight used in weighing and concentration calculations. It is added slowly to the solvent, as dissolving may release heat. The Magnesium Chloride Crystal Testing Reagent is available for supply within India and for export to New Zealand, Italy, Eswatini, Kyrgyzstan, Japan and Burkina Faso.
Frequently Asked Questions
Q1. Why does magnesium chloride need dry storage?
It is deliquescent and hygroscopic, so it takes up moisture from the air. A tightly closed container in a dry place keeps the hydrate form, and therefore the weighing figures, as labelled.
