The effect of pH on the sound velocity of solutions of various nucleosides and nucleotides has been studied. These velocity titration curves can be interpreted in terms of the changes in hydration which occur during this reaction. A procedure is presented to enable one to calculate the number, n, of protons which may titrate with a single inflection. In order to interpret the curves it is necessary to correct for the effects of ion binding and relaxational contribution to the sound velocity. Information about the change in hydration which accompanies ion pairing can be obtained from the velocity titration.
