Multiprotism Multiprotism Hydrogen ions are quite often referred to as protons , because that is all that is left of a hydrogen atom when its electron has been removed from it.
Some acids have the capability of providing more than one hydrogen ion from each molecule.
Such acids are called multiprotic . If an acid has more than one proton, it is called multiprotic . It is called di protic because it has two protons which can dissociate. There are a number of other acids that can dissociate to give two or even three protons. Those that give three protons are called tri protic.
