What happens to metal oxide when reacted with water?
- Metals form a respective metal oxide and hydrogen when reacting with water.
Metal + Water → Metal Oxide + Hydrogen
- Soluble metal oxide gets dissolved in water and form respective metal hydroxide.
Metal oxide + Water → Metal hydroxide
Example:
The reaction of Sodium with water
When sodium metal reacts with water, it gives sodium hydroxide and hydrogen gas. Sodium metal reacts so vigorously with water that hydrogen gas produced in this reaction catches fire immediately.
2Na+2H2O⟶2NaOH+H2
The reaction of Metal Oxides with Water
Most of the metal oxides are insoluble in water, but oxides of alkali metals and alkaline earth metals are soluble in water. Water-soluble metal oxides react with water and give their respective base. These bases are very strong and are called alkali.
Example:
The reaction of Sodium oxide with water
When sodium oxide reacts or dissolves in water, it gives sodium hydroxide.
Na2O+H2O⟶2NaOH
The reaction of magnesium oxide with water
When magnesium oxide is dissolved in water, it gives magnesium hydroxide.
Mg+2H2O⟶Mg(OH)2
