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.
What are the relative acidities of H3PO4 and H2PO4 -ion?
H3PO4 > H2PO4-PH 0.1 M SolutionsH3PO4 PH=1.5H2PO4- PH=4.4HPO42- PH=9.3PO43- PH=12
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.

What is the pH of the compound H3PO4?
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 procedure for conducting a titration using H3PO4 as the titrant?
To conduct a titration using H3PO4 as the titrant, first prepare a solution of H3PO4 of known concentration. Then, add the H3PO4 solution to the analyte solution (the solution being titrated) using a burette until the endpoint is reached. The endpoint is typically indicated by a color change or a sudden change in pH. Record the volume of H3PO4 solution used at the endpoint to calculate the concentration of the analyte.

Phosphoric acid H3PO4 is one of the components of blood and the intra cellular fluids that regulate the pH of bodily fluids What form of the acid are predominant at pH 3 pH7 and pH10?
I think your teacher will know. go ask him/her

Why is H3PO4 not a buffer system?
H3PO4 is not a buffer system because it is a weak acid that can only partially dissociate to release H+ ions. Buffer systems consist of a weak acid and its conjugate base, which can absorb or release H+ ions to maintain a stable pH. H3PO4 lacks a strong enough conjugate base to effectively buffer changes in pH.
