Classify the following salts as neutral,acidic or basic.Also,write their names. (a) Na3PO4 (b) K2CO3 (c) NH4NO3
Dear student,
The acidic, basic and neutral behaviour of the salt depends on the parent 'acids and bases' from which they are made.
So, in this case we have 3 salts i.e. Na3PO4 , K2CO3 and NH4NO3.
The acidic, basic and neutral behaviour of the salt depends on the parent 'acids and bases' from which they are made.

- Na3PO4:
Acid = H3PO4 (strong)
Base = NaOH (strong)
As this salt has been made from a strong acid and a strong base. Therefore, Na3PO4 is a neutral salt.
Base = NaOH (strong)
As this salt has been made from a strong acid and a strong base. Therefore, Na3PO4 is a neutral salt.
- K2CO3:
Acid = H2CO3 (weak)
Base = KOH (strong)
As this salt has been made from a weak acid and a strong base. Therefore, K2CO3 is a basic salt.
Base = KOH (strong)
As this salt has been made from a weak acid and a strong base. Therefore, K2CO3 is a basic salt.
- NH4NO3:
Acid = HNO3 (strong)
Base = NH4OH (weak)
As this salt has been made from a strong acid and a weak base. Therefore, NH4NO3 is an acidic salt.
Base = NH4OH (weak)
As this salt has been made from a strong acid and a weak base. Therefore, NH4NO3 is an acidic salt.
