Question

why na3po3 does not exist? ​

Answer 1

Answer:

na valency is 1 so it doesn't exist

Answer 2

H atoms that are bonded to O atoms can only be replaced

Explanation:

• $Na_3PO_3$ is a salt formed from the acid $H_3PO_3$
• $H_3PO_3$ is a dibasic acid because of a molecule of $H_3PO_3$ reacts with two molecules of a base
• In $H_3PO_3$, the two H atoms are bonded to O atoms and one H atom is bonded to P atom

∴ Only two H atoms that are bonded to O atoms can be replaced with two sodium atoms that form $Na_2HPO_3$.

Thus, $Na_3PO_3$  ​does not exist.
