Question

Explain the significance of CO3 in Na2 CO3?how is it different from Cl in Nacl??​

Answer 1

Sodium chloride formula is NaCl.

Sodium carbonate formula is Na

2 CO 3 The aqueous solution of sodium chloride is neutral because it is formed from a strong acid and a strong base.

Reaction: NaOH+HCl→NaCl+H 2O The aqueous solution of sodium carbonate is basic because it gets hydrolysed to some extent and forms sodium hydroxide which is a strong base and carbonic acid which is a weak acid.

Reaction of hydrolysis: Na 2 CO 3 +2H 2 O⇋2NaOH+H 2 CO 3.
