Orthophosphoric acid (H3PO4) have the following structure It is clear from the structure that it contains three replaceable hydrogen atoms, so it gives three H+ ions on dissolution in water. So, the basicity of H3PO4 is three H3PO4 longrightarrow 3H+ + PO3-4

Orthophosphoric acid $(H_{3} P O_{4})$ have the following structure
It is clear from the structure that it contains three replaceable hydrogen atoms, so it gives three H+ ions on dissolution in water. So, the basicity of $H_{3} P O_{4}$ is three
$H_{3} P O_{4} ⟶ 3 H^{+} + P O_{4}^{3 -}$
