Limiting Equivalent Conductances

Measurements have been made of the equivalent conductances of aqueous solutions of potassium iodate, potassium chlorate, and silver nitrate at 35.00 °C at concentrations ranging from 0.8 × 10−4 to 16×10−4 N. From these, the limiting equivalent conductances and association constants A as obtained by the use of the Fuoss–Shedlovsky extrapolation procedure were found to be at 35.0 °C:[Formula: see text]

Dilute Solutions

Conductances of dilute solutions of potassium iodate in water and water–dioxane solutions, extending over the dielectric constant range from D = 78.54 to D = 29.71, have been measured over the concentration range from zero up to Ka < 0.2 at 25.00 °C. By applying the Fuoss–Onsager treatment to the data obtained, the association constants for the electrolyte in the various solvents, as well as å, the distance of closest approach of the ions, have been determined.

Water Of Hydration

This paper is devoted to the direct determination of the vapor pressures of solutions of the nitrates of silver, of ammonium, and of lithium, at temperatures varying from 30 °C. to 105 °C. and at concentrations varying from 10 to 85 weight % (for lithium nitrate, the limited solubility precluded measurements beyond 65%). From the vapor pressures, the enthalpies of evaporation of water (by a modification of the Clapeyron–Clausius equation), the differential heats of dilution, and the activities of water (as compared with the mole fractions of the solvent) have been calculated. From the results we conclude that the water of hydration of the ammonium and silver ions (if, indeed, these ions are hydrated at all) is very loosely attached, while that of the lithium ion is strongly bound.

The Mean

Equivalent conductances, viscosities, and densities were determined for solutions equimolar in two of the three salts lithium nitrate, ammonium nitrate, and silver nitrate. The three possible combinations of two salts were each studied at 25 °C and at 35 °C.The observed conductances and viscosities were compared with those of the single salt solutions at the same total ion concentration. The conductances were lower than the mean of the conductances of the single salt solutions. The viscosities were also lower than the mean viscosities.

Limiting Equivalent Conductances

Equivalent conductances, densities, and viscosities of aqueous solutions of sodium octanoate have been determined at 25° and 35 °C, at concentrations ranging from 0.0002 M to 2.8 M. The limiting equivalent conductances of the octanoate ion have been determined as 23.08 mhos and 29.09 mhos, at 25° and 35 °C respectively.Comparison has been made of our experimental conductances with those calculated, using the equations of Robinson–Stokes, of Falkenhagen–Leist, and of Fuoss.No evidence has been found of micelle formation in solutions of sodium octanoate.
