Question

Show the ionization and salt formation of tribasic acid

Answer 1

The ionization and salt formation of a tribasic acid is given below:

- Let AH₃ be a tri- basic acid.

- The ionization of AH₃ in water is given as:

AH₃ ⇄ 3 H⁺ + A³⁻

- The salt formation of AH₃ upon reaction with base NaOH is given as:

AH₃ + 3 NaOH ⇄ Na₃A + 3H₂O

- Phosphoric Acid (H₃PO₄) is a tribasic acid and its ionization and salt formation takes place in the same manner as above.
