The basicity of an acid may be defined as the number of combining protons.
Mono-basic : hydrochloric acid (HCl) - 1 x proton.
Mono-basic : nitric acid (HNO3) - 1 x proton
Di-basic : sulphuric acid (H2SO4) - 2 x protons
Di-basic : A carboxylic acid that has two 'acid' functional groups such as ethan-di-oic (Oxalic) acid
Tri-basic : phosphoric acid (H3PO4) - 3 x protons

Should it not be diprotic? Anyway sulphuric acid loses two protons (H+) whilst NaOH accepts one. So if you are using an indicator to see when the mixture becomes neutral than you will need twice as many moles of NaOH as H2SO4, proving that H2SO4 is diprotic.
