Abstract

The relative sound velocities (u—u °) of aqueous HCL, LiCL, NaF, NaCL, NaBr, Nal, NaN03, NaOH, NaHC03, Na2S04, KF, KCL, KBr, KI, KN03, K2C03, K2S04, RbCl, CsCl, NH4C1, NH4Br, MgCh, CaCl2, SrCl2, BaCl2and MgS04solutions were measured from 0.01 to 1.0 at 25°C. The sound velocities were fitted to a function of molality (maximum standard deviation 0.05 msec'1) u = u ° + Am + Bm^/2>> Cm2, where u° is the sound velocity in pure water, and A, B, and C are temperature dependent parameters. The adiabatic compressibilities f3swere determined from the sound velocities and were used to calculate the adiabatic apparent molal compressibilities ϕk(s)of the salts. The ϕkand βsof seawater were estimated by using Young's rule. The calculated values of ϕKand βsagree with those determined from the measurements on seawater solution to ±0.18X 10-4cm3mol-1bar-land ±0.004X 10-6bar-l. The sound speeds of seawater calculated from the values of βsestimated from Young's rule agree on the average to ±0.02 msec-1(maximum standard deviations 0.07 msec-1) with the direct measurements of Millero and Kubinski.
