Abstract

The apparent molal volumes, ΦV's, of dilute (0.002-0.1 m) aqueous solutions of tetraphenyl arsonium chloride (Ph4AsCl) have been determined at 0°, 25°, and 50°C from precision density measurements. The ΦV's, as a function of (c)>1/2, approach limiting law behavior at all the temperatures studied. The deviations of the ΦV's from the limiting law are positive at 0°, and negative at 25° and 50°C. The ΦV's at infinite dilution have been extrapolated with the aid of the limiting law. The effect of temperature on the Φ°V's of the Ph4AsCl solutions is similar to other commnn electrolytes, in that ρ2Φ°V/ρT22Φ°E/ρT is negative. The ion-ion and ion-water interactions responsible for the observed behavior of the ΦV's, for Ph4AsCl solutions are briefly discussed.
