IONIZATION COEFFICIENTS OF CERTAIN 



TABLE II. 



It appears from these results that in the case of solutions of 

 potassium sulphate the ionization coefficient increases very 

 slightly with rise of temperature between and 18C from a, 

 concentration of 0.05 to one of about 0.35, and that from this 

 ntration to one of at least 0.7 it decreases, the magnitude of 

 the decrement increasing rapidly with the concentration, and 

 amounting at a concentration of 0.7 to 5 per cent. In the case 

 of sodium sulphate, the coefficient diminishes with rise of
