Concerning the chemical form of H 3 PO 4 after the first H + has completely come off (which occurs when the pH has risen above 3 or so) we are left with H 2 PO 4 - But since Na + is also left by this reaction (the OH-and the H + having combined to produce water) we can express the ions in solution as being Na + H 2 PO 4 - or just NaH 2 PO 4 (also called monobasic sodium phosphate)

05 09 2017The pKa value of sodium phosphate monobasic is 7 21 at 25C and serves as an acid in this buffer because it is more acidic than sodium phosphate dibasic The molecular weight of sodium phosphate monobasic is 120 and of sodium phosphate dibasic is 142 Answer Save 1 Answer Relevance hcbiochem

08 12 2011This is now a dibasic phosphate ion since it already has one hydrogen so therefore can only accept two more H2PO4 - is monobasic since it already has two H+ ions so can only accept one more So in your question monobasic sodium phosphate is NaH2PO4 di basic sodium phosphate is Na2HPO4 So it is the concentration of these that we are trying to
