An ionic bond is formed in Al2(CO3)3

Explanation:

  • Al2(CO3)3 aluminium carbonate is the aluminium salt of carbonic acid.
  • A chemical bond is said to ionic if the bond is formed due to the electrostatic attraction between any two oppositely charged bodies.
  • Ionic bonding is the interaction that takes place between anions and cations in ionic compounds.
  • The formula of aluminium carbonate - Al2(CO3)3 denotes that there are 3 carbonate ions for every 2 aluminium ions.
  • Aluminium is a metal and loses three electrons and forms a 3+cation. Carbonate is polyatomic anion with formula CO2-3.
  • Hence, an ionic bond is formed between the aluminium cation and carbonate anion
