Question

How to find number of replaceable H
+ ions and OH- ions

Answer 1

Basicity is the number of replacable hydrogens of an acid in aqueous or basic medium. Three –OH are present (attatched with P atom ) . Number of replaceable hydrogen ions in H3PO4 is 3

Answer 2

To find number of replaceable H + ions and OH- ions

Explanation:

• Basicity of acid is the no of ionizable hydrogen $H^+$ ions existing in one molecule of an acid is known basicity.  Basicity of an acid rely upon the number of free hydrogen ions  $H^+$  existing in the solution.

• Acidity of base is the no of ionizable hydrogen ions $OH^-$existing in one molecule of a base is known acidity. Acidity of a base rely upon the number of free hydroxyl ions  $OH^-$   existing in the solution.
