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)

Is magnesium oxide aqueous?

No. Magnesium oxide is not soluble in water. On contact with water it will form magnesium hydroxide.


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.


Is milk of magnesia a heterogeneous mixture?

Yes, milk of magnesia is a heterogeneous mixture. It contains insoluble solid particles of magnesium hydroxide suspended in a liquid, resulting in a mixture with visibly different components that do not fully dissolve.


Is this equation correct Magnesium Hydroxide heat up will give Magnesium Phosphate plus water?

No - phosphorous can not just appear.Heating magnesium hydroxide will give magnesium oxide and water.


Difference between magnesium oxide and magnesium hydroxide?

Magnesium oxide is formed by burning magnesium in the presence of oxygen, while magnesium hydroxide is formed by reacting magnesium oxide with water. Magnesium oxide is more commonly used as a supplement for magnesium deficiency, while magnesium hydroxide is often used as an antacid or laxative due to its ability to neutralize stomach acid and promote bowel movements.

What happens when magnesium oxide is added to water the salt will be?

When magnesium oxide is added to water, it will react to form magnesium hydroxide, a salt solution, and release heat. This reaction is exothermic and the magnesium hydroxide formed will be a white solid that will dissolve in water to form the salt solution.

Will a strong alkali dissolve in water?

All types of strong alkali do not dissolve well in water. Magnesium hydroxide can be given as an example for an insoluble strong alkali.


What happens when magnesium oxide dissolve in water?

When magnesium oxide dissolves in water, it forms magnesium hydroxide. This reaction results in the release of heat (exothermic reaction) and increases the pH of the solution. Magnesium hydroxide is a weak base that can help neutralize acids in the stomach, making it useful in antacid medications.

Magnesium hydroxide. Most people are familiar with it when it is suspended in water to make Milk of Magnesia.


What is the metal that reacts slowly with cold water to form a hydroxide?

The metal that reacts slowly with cold water to form a hydroxide is magnesium. When magnesium reacts with water, it forms magnesium hydroxide and hydrogen gas.

Bases which do not dissolve in water?

Bases that do not dissolve in water include some insoluble metal hydroxides like magnesium hydroxide, calcium hydroxide, and barium hydroxide. These bases tend to form precipitates when added to water instead of fully dissolving.
