Calcium Chloride vs. Magnesium Chloride: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Published on January 31, 2024
Calcium chloride (CaCl2) is a salt used for de-icing and dust control, while magnesium chloride (MgCl2) is used for similar purposes but is less harsh on the environment.

Key Differences

Calcium chloride, a chemical compound with the formula CaCl2, is known for its high solubility and hygroscopic nature. In contrast, magnesium chloride, MgCl2, also highly soluble, tends to be less hygroscopic. Both are used in de-icing and dust control, but calcium chloride is more effective at lower temperatures.

In terms of industrial applications, calcium chloride is widely used in oil drilling and as a drying agent due to its hygroscopic properties. Magnesium chloride, on the other hand, finds extensive use in the preparation of magnesium metal and as a coagulant in tofu manufacturing. Both are crucial in their respective sectors for their unique properties.
