Sodium oxide Na2O is a basic oxide, when interacting with water forms an alkali – sodium hydroxide.

Na2O + H2O = 2NaOH.

Basic oxides react with acids. As a result of the reaction between acid and alkali, salt is formed – sodium sulfate and water.

Na2O + H2SO4 = Na2SO4 + H2O.

Basic oxides react with acidic oxides. A salt of the acid is formed, which corresponds to the acidic oxide. The product of the reaction between sodium oxide and sulfur (VI) oxide is sodium sulfate.

Na2O + SO3 = Na2SO4.

Acidic oxides react with water to form acids.

H2O + SO3 = H2SO4.

Sulfuric acid reacts with potassium hydroxide to form potassium sulfate and water.

H2SO4 + 2KOH = K2SO4 + H2O.

Magnesium with dilute acid reacts with the evolution of hydrogen and the formation of magnesium sulfate.

Mg + H2SO4 = MgSO4 + H2.

Magnesium reacts with hot water to form magnesium hydroxide and hydrogen.

Mg + 2H2O = Mg (OH) 2 + H2.
