Commonly applied in the production of magnesium metal and as a coagulant in the preparation of tofu from soy milk. Employed in medical treatments for magnesium deficiency and as an electrolyte in certain types of batteries. Utilized in agriculture as a fertilizer supplement for magnesium-starved soils, supporting chlorophyll production in plants.
