Magnesium oxide does not "dissolve" in hydrochloric acid. Dissolution is a physical change. When magnesium oxide is mixed with hydrochloric acid, a chemical reaction takes place:

Mg(s) + 2HCl ---> MgCl2(aq) + H2(g)

Why does barium hydroxide dissolve in water while magnesium hydroxide does not?

One factor is that barium is a much larger atom and ion than magnesium. So the bond between barium and the hydroxide anion is much weaker, making it easier for the two ions to be pulled apart in water solution.


Common name for magnesium hydroxide?

Magnesium hydroxide is an inorganic compound with the chemical formula Mg(OH)2. As a suspension in water, it may be referred to as Milk of Magnesia. The solid mineral form of magnesium hydroxide is known as brucite.Magnesium hydroxide is common component of antacids and laxatives. Magnesium hydroxide interferes with the absorption of folic acid and iron.Magnesium hydroxide is not very soluble in water, with a Ksp of 1.5x10-11. While the solubility of magnesium hydroxide is low, all of the magnesium hydroxide that does dissolve in the water does dissociate. Since the dissociation of this small amount of dissolved magnesium hydroxide is complete, magnesium hydroxide is considered a strong base.
