Is H2Mg soluble

Hydride of magnesium (H2Mg) is not a commonly encountered compound, and its solubility can vary depending on the specific conditions. Generally, metal hydrides, including those of alkaline earth metals like magnesium, have low solubility in water. However, they can react with water to produce hydrogen gas and magnesium hydroxide, which is also insoluble. Thus, H2Mg is considered insoluble in water.
