You are able to measure the undissociated fraction (i.e., H3BO3), and you Chemistry. a) H3PO4 (aq) -> 3H+(aq) + PO4-3(aq) b) H3PO3 (aq) -> 3H+(aq) + PO3-3(aq) Phosphorous acid | H3PO3 or H2[HPO3] or H3O3P | CID 107909 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more. H 3 PO 4 contains three elements phosphorous, oxygen and hydrogen. The dissociation constant (K) for equation 3 is only about 1/400 of the dissociation constant (K') of equation 2 because the proportionality ratio between H2CO3 and CO2 is 1:400. www.scifun.org .
