For water solvent the transference number of silver ion in silver perchlorate decreases slowly but linearly with decreasing concentration of the salt and extrapolates to 0.488 plus or minus 0.005 at infinite dilution. This value agrees quite well with values for dilute solutions recorded in the literature. The moles of water carried per mole of cation increases with decreasing weight per cent silver perchlorate, as is to be expected and is in agreement with the decrease of the transference number with increasing weight per cent ethanol. There was first a small linear decrease of transference number of the silver ion with increasing weight per cent ethanol to about 55 wt.% ethanol. Then there was an accelerated rate of decrease of the transference number up to about 85 wt.% ethanol when the rate of decrease again decelerated. The solvation data indicated that silver ion carries an excess of water compared to the perchlorate ion whereas the perchlorate ion seems to carry alcohol molecules in an amount equal to or greater than the silver ion, depending on how the basis of comparison is determined. These data might be interpreted as showing selective solvation of silver and perchlorate ions by water and ethanol, respectively. (auth)
