Is Magnesium Water Soluble?
Solubility of Magnesium Compounds in Water
Magnesium, in its various compound forms, exhibits different levels of water solubility. For instance, magnesium-l-ascorbate, magnesium-l-glutamate, and magnesium-d-gluconate have been studied for their solubility in water across a range of temperatures from 278.15 K to 343.15 K. These studies indicate that these magnesium compounds are indeed soluble in water, allowing for the evaluation of their apparent molar enthalpies of solution .
Water-Soluble Magnesium Sulfate
Magnesium sulfate, commonly known as Epsom salt, is another magnesium compound that is highly water-soluble. Research has shown that magnesium sulfate bonded sand core materials possess good water solubility, high curing speed, and strength. The water-solubility rate of these materials is significant, making them suitable for various industrial applications, including casting . Additionally, magnesium sulfate forms hydrates that are stable at different temperatures, further demonstrating its solubility in water .
Magnesium in Drug Delivery Systems
Magnesium compounds are also utilized in drug delivery systems to enhance the solubility of poorly water-soluble drugs. For example, mesoporous magnesium carbonate (MMC) has been used as a drug carrier to achieve supersaturation of drugs with low aqueous solubility. This indicates that magnesium compounds can play a crucial role in improving the solubility and bioavailability of certain pharmaceuticals .
Magnesium Chloride and Water Solutions
Magnesium chloride is another highly soluble magnesium compound. When dissolved in water, it forms structured solutions with hydration spheres around the ions. This solubility is crucial for various chemical and industrial processes .
Magnesium Oxychloride Cement
The addition of soluble phosphates to magnesium oxychloride cement significantly improves its water resistance. This is due to the formation of stable phases in the cement that do not decompose in water, indicating that magnesium compounds can be engineered to enhance their water resistance properties .
Magnesium Triglycine Chelate
A novel magnesium triglycine chelate has been synthesized, showing extraordinary water solubility and improved cellular uptake compared to other magnesium supplements. This chelate is designed to counteract magnesium deficiency and is highly bioavailable, making it a promising candidate for clinical applications .
Conclusion
In summary, magnesium in various compound forms exhibits significant water solubility. Compounds such as magnesium sulfate, magnesium chloride, and magnesium-l-ascorbate are highly soluble in water, making them useful in a wide range of applications from industrial processes to pharmaceutical formulations. The solubility of magnesium compounds can be further enhanced or modified through chemical engineering, as seen in the development of water-resistant magnesium oxychloride cement and highly soluble magnesium chelates.
