Abstract

The apparent molal volumesΦV′s, of dilute (0.002-0.1m) 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 Ö/s at infinite dilution have been extrapolated with the aid of the limiting law. The effect of temperature on the ΦV′0s of the Ph4AsCl solutions is similar to other common electrolytes, in that ∂2ΦV0/∂T2 = ∂ΦE0/∂T is negative. The ion-ion and ion-water interactions responsible for the observed behavior of the ΦV′s for Ph4AsCl solutions are briefly discussed.
