Aspect of Electrolytic Conductance

Attempts at establishing a correlation between dielectric constant and electrolytic strength in these systems were described as unsuccessful. The term phoreogram was used to designate the plot of the equivalent conductance (A) vs the square root of the concentration According to the following order of electrolytic 

This correlation conflicts strongly with the interpretation of the Xhx values as shown in Tables 13A and 13D. For n-octanol, the equivalent conductance would probably be very small, and at 0°C and Phx = 1 atni the proportion of the (about) 1 mole of HX per mole of -octanol which gives rise to ions on a time-average basis must be very small. 

According to Guss and Kolthoff (1940), the strong acid is completely ionized into ROH2 and anions, and water is a much stronger base than the alcohols such as methanol, ethanol, and n-butanol. A scrutiny of the Xhx vs Phx plots puts such statements in their proper focus in a remarkable way. At 0°C and Phx = 5mmHg, the xhx value for water is larger than that for n-octanol but at Phx = 1 atm, the Xxh values for water are only about half of the values for the alcohol. 

Janz and Danyluk referred to liquids such as nitrobenzene as nonbasic, although that compound was described as polar. The weakly acidic properties of the nitro group were said to limit the utility of nitrobenzene and nitromethane as ionizing media for the hydrogen halides. It was also stated that hydrogen chloride and hydrogen bromide are very weak electrolytes in acetic acid. 

At 10°C, 1 mole of CH3COOH absorbs about 0.19 mole of HCl at Phci = 1 atni, thus showing a definite basic function toward HCl. According to the A data, A for this strongest solution must be very small indeed, meaning that most of the HCl is hydrogen-bonded as
