The pH of any substance depends upon its concentration in the solution.

But in general orthophosohoric acid is a weak acid and hence has higher pH than acids like Nitric acid, sulphuric acid at the same temp. and concentration.

What is the pH of H3PO4?

The pH of H3PO4 (phosphoric acid) depends on its concentration. For a 1M solution, the pH would be around 0.91. Since phosphoric acid is a weak acid that can donate three protons, its pH decreases with increasing concentration due to the dissociation of H+ ions.

At pH 7.5 which species predominate of H3PO4?

HPO42- is the most abundant phosphate present at pH=7.5, but H2PO42- is also there in (less) significant amounts. PO43- and H3PO4 are practically absent at pH 7.5.This is because it is between the valuespH=pKa,3= 12.4 (at which value there is 50% HPO42- and 50% PO43-) andpH=pKa,2= 7.2 (at which value there is 50% HPO42- + 50% H2PO42-)[Cf.
