Sodium carbonate is Na2CO3

Aluminium oxide is Al2O3

Answer 2

The chemical formula of Sodium Carbonate is Na₂CO₃ and Aluminium Oxide is Al₂O₃.

Explanation:

The chemical formula of Sodium Carbonate is Na₂CO₃ and Aluminium Oxide is Al₂O₃.

• Sodium Carbonate Na₂CO₃

• It is a disodium salt of carbonic acid. It is a also known as 'soda ash'.
• Earlier it used to be obtained from the ashes of plants growing in areas with sodium rich soils, hence the name Soda ash. Today it is produced in various forms to meet the industrial need in the forms of sodium chloride and limestone.
• Most of its forms are white, odorless, soluble in water, alkali, glycerol, aqueous alcohol, etc. When dissolved in water they dissociate to form carbonic acid and sodium hydroxide.
• They are mild alkaline solutions are are used to act on acids.

• Aluminium oxide (Al₂O₃)
• It is a  naturally occurring compound of aluminium and oxygen. It is commonly known as Alumina.
• It is a white odorless solid, insoluble in all solvents.
• Because of it high melting point it is used in the production of aluminum metal.
• It is widely used in the production of ceramics.
• Mostly found in crystalline form. The commonly found crystalline form, corundum is found to have several gem quality variants.
