Im doing a biology paper about the pH buffer Tribasic Phosphate, and am finding a great deal of difficulty finding anything about "tribasic phopshate" anywhere. Can anyone either give me websites that have tons of info on it, or tell me everything you know about tribasic phosphate and PLEASE INCLUDE SOURCES because otherwise i cannot use the information you provide.

im not looking for potassium dihydrogen phosphate or potassium hydrogen phosphate or potassium phosphate ... im looking for tribasic phosphate which i was told by my professor has a pKa of 12.7 , 7.2 and 2.1

You biology professor is a poor chemist. The term Tribasic phosphate is a very general one going back centuries. It includes the phosphate salts with just about any light metal cation. This would include Lithium, Sodium, Potassium, Calcium, Magnesium and others.
I am sure that he means either Sodium Phosphate or Potassium Phosphate as these are the most common. Since you believe that it is not the Potassium salt then it must be:
Sodium Phosphate, Tribasic (CAS = 7601-54-9)
as the official designation. This is also known as Trisodium Phosphate or TSP.
The sodium salt (Na3PO4) is also consistant with your pka data.
If you still need more help, add details to your question.

"am finding a great deal of difficulty finding anything about "tribasic phopshate" anywhere"
Maybe if you spelled it correctly?
