226 PROPERTIES OF ELECTRICALLY CONDUCTING SYSTEMS 



M* differs from X~, y s is not identical with the ionization of the salt, 

 but, unless the hydrolysis is great, the value of y s will not differ appre- 



ciably from that of the salt at the concentration in question. Let h 

 represent the total fraction of base present in the un-ionized condition, 

 in which case h is the hydrolysis coefficient. A solution of the above 

 equations leads to the equation: 



(55) 



The concentrations of the various constituents are given by the follow 

 ing equations: 



C - 



K b h 



(l-h) Kh 



K 

 (56) OH- = 



K b h 



_ _ 



MOH = hC b 



If Y S , together with the reaction constants, are known, the concen- 



trations of the constituents may be calculated. The equations may be 

 generalized by introducing the ionization function K S for the salt by 

 means of the equation: 



(57) M+ X X- = S MX. 



This leads to the equation:
