Basicity of Acids

  1. Basicity of an acid is the number of hydrogen ions which can be produced by one molecule of the acid.
  2. There are 3 common types of Basicity of an acid
    1. monoprotic
    2. diprotic
    3. triprotic

Monoprotic Acids

The monoprotics acids are the acids that produced 1 H+ ion from each acid molecule.
Example
HCl  H 2 O H + +C l HNO 3   H 2 O H + +N O 3 CH 3 COOH H 2 O C H 3 CO O + H +

Diprotic Acids

The diprotics acids are the acids that produced 2 H+ ion from each acid molecule.
Example
H 2 SO 4   H 2 O 2 H + +S O 4 2 H 2 SO 3   H 2 O 2 H + +S O 3 2 H 2 CO 3 H 2 O 2 H + +C O 3 2

Triprotic Acids

The triprotics acids are the acids that produced 3 H+ ion from each acid molecule.
Example
H 3 PO 4   H 2 O 3 H + +P O 4 3
