Acids Bases Problem Set

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)
