## Abstract The titration curve of ultrasonic absorption at 2.82 MHz in aqueous solutions of lysozyme measured by Zana and Lang [__J. Phys. Chem.__, **74**, 2734 (1970)] is theoretically analyzed. The maxima at pH 3 and pH 11 are describable with protonβtransfer reactions of dissociable carboxyl an
Values of A V for carboxyl and amino groups in the Synopsis and Table I were erroneously given and should read 9.4 and 19.7 cm3/mole, respectively. Consequently, the statement on page 788 that the bV is considerably smaller than that for glycine should be deleted. The value of A V for carboxyl group
The excess ultrasonic absorption in ionic solutions is explained on the basis of the molecular motions of solvent molecules at various distances frcm the ions. A comparison between experimental and theoretical results for pure water and for aqueous solutions of LiCl and KBr shows good agreement.
