Straight Line

The specific and equivalent conductances (which also involve the densities) of aqueous solutions of silver nitrate and of ammonium nitrate, ranging in concentration from 0.1 M to that of the pure molten salt, have been determined at temperatures of 221.7 °C and 180.0 °C, respectively. It has been found that when the equivalent conductance is plotted against logarithm of the concentration, a straight line is obtained in the region of concentrations greater than about 6 M or less. Hence the equivalent conductance can be calculated from the relation[Formula: see text]where D = the slope and Λa = equivalent conductance at the limiting experimental concentration, Ca (in the molten state).

Measurements of conductance and fluidity of silver nitrate and of ammonium nitrate solutions, over a range of concentration varying from 0.05  N to 14  N (silver nitrate) and from 0.08  N to 15  N (ammonium nitrate) have been made. In both cases, a maximum is observed in the specific conductances but in neither case does a minimum occur in the plot of equivalent conductance against concentration. While the equivalent conductance in very dilute solutions is proportional to [Formula: see text], in very concentrated solutions it appears to be directly proportional to C. Temperature coefficients of conductance and of fluidity are evaluated and their theoretical importance discussed. Partial molar volumes of water in these solutions are evaluated.

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.

Medium Concentration

Equivalent conductances, densities, and viscosities of aqueous solutions of ammonium nitrate, of silver nitrate, and of lithium nitrate were determined at 25 °C and at 35 °C at concentrations ranging from 0.01 N to 1.0 N.Experimental equivalent conductances have been compared with those calculated by the Wishaw–Stokes and Falkenhagen–Leist equations. Suitable choice of one parameter, the distance of closest approach, permits reproduction of the experimental data with an error of less than 0.5%. A study of the deviations of the calculated from the experimental conductances reveals that the distance of closest approach (so-called) varies appreciably with concentration and temperature.

The transference numbers, equivalent conductances, densities, and viscosities of aqueous solutions of silver nitrate and of silver perchlorate have been determined from a concentration of 0.1 M up to 7.6 M, for silver nitrate, and up to 5.6 M for silver perchlorate. In both cases the cation transference number increases considerably with increasing concentration. Certain anomalies in the results for silver perchlorate raise the possibility of complex ion formation here. Similar anomalies appear in the behavior of equivalent conductance with respect to concentration.The results of the conductance measurements have been compared with the values calculated from the equations of Wishaw and Stokes and of Falkenhagen and Leist.

The density, viscosity, and electrical conductivity of highly concentrated solutions of ammonium nitrate in dimethyl sulphoxide have been determined over the temperature range 10-60 °C and the concentration range 7-50 mol% of the salt. The variations in the quantities as a function of temperature and concentration have been correlated by empirical equations. A comparison is made between the transport properties for the present system, aqueous solutions of ammonium nitrate, and calcium nitrate solutions in dimethyl sulphoxide.
