Acids in salt solutions

The last paper (S30) presented activity coefficients for the undissociated part of the following weak electrolyte acids benzoic, ortho toluylic, salicylic, ortho-nitrobenzoic, acetic, monochloracetic and dichloracetic acids. In a study of binary solutions of sodium and potassium acetate. RandaU. McBain and White (S26) found the ionic activity coefficients to be very close in value to the ionic activity coefficients for binary sodium and potassium chloride solutions. Consequently, in Randall and Failey s paper on the activity coefficients of the undissociated part of weak electrolytes, the activity coefficients of the monobasic acids in salt solutions oi varying concentrations were assumed to be equal to the activity coefficient of hydrochloric acid in the same or similar salt solution at the same concentration. This meant that ... 

The activity coefflcients of the undissociated portions of the weak acids were calculated in the following manner using data presented by numerous authors of the solubility of the weak acid in salt solutions of varying concentrations ...
