### Abstract

The speeds of sound in aqueous solutions of NaCl, MgCl//2, Na//2SO//4, and MgSO//4 have been measured relative to pure water from 0 to 1 molal ionic strength, 0 degree to 55 degree C, and 0 to 1000 bar applied pressure. The 1-atm results have been fitted to polynomial equations of concentration and temperature with standard deviations of about 0. 1 m/s, U**0 minus U//W**0 equals am plus bm**3**/**2 plus cm**2 where U//0 and U//W**0 are the 1-atm sound speeds in solution and in pure water, respectively; m is molality; and a,b, and c are temperature-dependent parameters. The effect of pressure on the relative speeds of sound has been fitted to equations of the form (U**P minus U//W**P) minus (U**0 minus U//W**0) equals dm plus em**3**/**2 plus fm**2, where U**p and U//W**p are the sound speeds of the solution and water at applied pressure P and d,e, and f are temperature- and pressure-dependent parameters. The standard deviations of the least-squares fits are within 0. 12 m/s for all the salts.
