Polybasic weak acids indistinguishable from monobasic ones by acid-base titrimetry

Presents a general equation describing the statistical ratio of the ith an (i + 1)th dissociation constants of a j-basic acid and shows that any such acid whose dissociation constants conform to those ratios will give a titration curve indistinguishable from that obtained for a monobasic acid at an appropriate concentration.
