Abstract
The apparent molal adiabatic compressibilities of NaCl, KCl, NaBr, and KBr in water have been measured in the concentration range from 0.01 to 1 mol kg−1 at 5, 25, and 45 °C. The results have been fitted to a Redlichtype equation: φKs=φKs°+SKsc1⁄2+BKsc. The limiting slope, SKs, was found experimentally as 5.6×10−4 at an ordinary temperature. Convenient equations for the conversion of adiabatic to isothermal compressibilities have been derived; the limiting slope for isothermal compressibility, SKT, should be larger than SKs at all the temperatures studied. The value of SKs determined experimentally has been compared with that predicted from the SKT values calculated by Mathieson and Conway, by Millero, and by Bradley and Pitzer.This publication has 21 references indexed in Scilit:
