Expert Answer:

Basicity of an acid is defined as the number of hydronium ions that can be produced by the ionisation of one molecule of that acid in aqueous solution.
 
Acids which, on ionisation in water, produce two hydronium ions  per molecule of the acid are dibasic acids for ex: sulphuric acid.
 
Acids which on ionisation, prodcue three hydronium ions per molecule of the acid are called tribasic acids for ex: phosphoric acid.
