how does free ionizable hydrogen atoms in POH bond  oxacids help in basicity?

Expert Answer:

The P-H bonds are not ionisable to give H+ and do not play any role in basicity.
While H atoms which are attached with oxygen in P-OH form are ionisable and cause basicity.
For example H3PO3 and H3PO4 are dibasic and tribasic respectively.
