The experimental dissociation constant K of weak electrolytes may be consldered as derlved from dlfferent contributions due to the Ionization, K,,and dlssociation, Kd,equlllbrla, respec- tively. AsimplemethodforK,andKdevaluatlonisherein proposed, startlng from experimental K data, obtained by the conductometric method, for plcrlc acld in a set of binary solventsystemmixturesattemperaturesrangingfrom-10 to +80 O C . The correlatlonsbetweenK,and Tand betweenK, and Tare moreover suggested on the basis of a general ex- pression derlved from the Integrated Van’t Hoff equation.
