ABSTRACT
The speeds of sound in both H2O and D2O solutions of Me4NBr and n-Bu4NBr have been measured at molalities up to 3.0 mol*kg-1 at temperatures of (283.15, 298.15, 318.15, and 338.15) K and at a pressure of 0.1 MPa with a single-crystal variable-path interferometer of uncertainty +- 0.5 m*s-1.
