Compressibilities of Sodium and Potassium Hydroxides

Abstract

GUCKER1, on the basis of the Debye–Hückel theory, found that the apparent molar compressibility of aqueous solutions of electrolytes conforms to the relation ϕ(k 2) = ϕ0(k 2) + S k C 1/2, where ϕ(k 2) is the apparent molar compressibility at molar concentration C and ϕ0(k 2) at infinite dilution. S kis a constant. Similarly, the adiabatic compressibility was found to follow the relation β = β0 + AC + BC 3/2 (Bachem2), where β is the adiabatic compressibility at molar concentration C and β0 is that of water, while A and B are constants.
