For oxyacids no. of OH groups in structure = basicity Orthophosphoric acid is H3PO4 <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/b6af53c6c6b4290d01b2a4902c7da93a-.png" /> ∵ H 3 PO 4 has 3-OH groups in structure ∴ It is tribasic acid.

Q. Orthophosphoric acid is:

monobasic

dibasic

tribasic

tetrabasic

For oxyacids no. of OH groups in structure = basicity
Orthophosphoric acid is $H_{3} P O_{4}$

$∵ H_{3} P O_{4}$ has 3-OH groups in structure
$∴$ It is tribasic acid.
