Solutions of half-electrolytes

The symbol of equilibrium for, say, acetic acid, C2H,0, C2H30, + H, gives us from the general equation k = 2tilog(7 

The value of K under the logarithmic sign, whose constancy at constant temperature has already been shown (p. 118), has been found to possess at 10° and 40° the (mean) values shown in the following table Thence q is calculated according to 

Here q is the heat that would be developed—no external work being done—if a kilogram-molecule of acid were 

Calorimetrically this quantity may be found as the difference between the heats of neutralization and of dilute nitric and, say, acetic acid by a dilute strong base. For 

The values of — have been found to be very small, in accordance with the preceding theory
