Sztmmary E.m.f. measurements with Ag-AgC1 and with Ag-AgBr electrodes yield association constants for the formation of CdX+ and CdX, in molten Ca(N0,),,4Hz0; the bromide results confirm previous measurements with Cd-Hg electrodes and with dropping Hg electrodes, and the chloride results yield ratios of second to first association constants similar to those in anhydrous molten salts, revealing no s t ~~~t u r a l ~n~lrlafies caused by the presence of water.halide and of cadmium. Plots of (l/y& -1 and (I/& -1 are shown in Figure 2 along with the slopes whose extrapolation1p6 leads to the values of K, and K , in the Table .$ The linearity of (l/yBr) -1 makes evaluation TABLE Association Constants of CdII with C1-or Br-in molten Ca(NO,),, K,(CdCl+) fl hCF$# K,(CdBr+) K,(CdBr,) 4H,O at 40 O C (mol/mol Cat-1 ASSOCIATION constants for dilute solute species in concentrated aqueous electrolytic solvents and their com-* 6o 3900 rfr: 200 1400 -& 100
