39. Fosforik asit (H3PO4) bir triprotik zayf asittir. pH' hesaplayn, [H3PO4], [H2PO4 -], [HPO4 2-] ve [PO4 3-] 4.5 M H3PO4 sulu zeltisi. H3PO4 (sulu) + H2O (l) H3PO4 - (sulu) + H3O+ (sulu) Ka1 = 7,5 10-3 H3PO4 - (sulu) + H2O (l) HPO4 2- (sulu) + H3O+ (sulu) Ka2 = 6,2 10-8 HPO4 2- (sulu) + H2O (l) PO4 3- (sulu) + H3O+ (sulu) Ka3 = 4,2 10-13
