Asam poliprotik

Although the subsequent loss of each hydrogen ion is less favorable, all of the conjugate bases are present in solution. The fractional concentration, "α" (alpha), for each species can be calculated. For example, a generic diprotic acid will generate 3 species in solution: HA, HA, and A. The fractional concentrations can be calculated as below when given either the pH (which can be converted to the [H]) or the concentrations of the acid with all its conjugate bases:
