What is Basicity of Acids

 

The basicity of an acid is the number of hydrogen ions, which can be produced by one molecule of the acid. The table below shows some acids and their basicity.

Acid

Basicity

HCl        H+ + Cl-

H2SO4 2H+ + SO42-

H3PO4     3H+ + PO42-

CH3COOH   H+ + CH3COO-

1 Monobasic

2 Monobasic

3 Monobasic

1 Monobasic

 

Note: It isn’t in all cases that a compound furnishes all its containing hydrogen atoms as ions. Example, in ethanoic acid.

When 1 mole of hydrogen ions is furnished from 1 mole of an acid, the acid is monobasic; it is dibasic when 2 moles of hydrogen ions are furnished, and tribasic when 3 moles of hydrogen ions are furnished from 1 mole of its solution.
