430 DETERMINATION OF THE FREEZING-POINT DEPRESSIONS 
The table also contains the values of the depression constant, 
2. @., the lowering produced by each gramme-molecule or gramme- 
ion of the electroyte in solution. It has been calculated by aid 
of the expression: 6=7 (1+) where 6 is the equivalent depres- 
sion, 7 is the constant and ais the ionization coefficient. This 
formula only holds for electrolytes such as KCl where the 
gramme-molecule is equal to the gramme-equivalent and the 
molecule breaks up into two ions.
