LAWS OF ELECTROLYTIC DISSOCIATION 93 



of moderate strength is to measure the [H+] in a pure solution of 

 the acid and to calculate k by applying equation (la) on page 40. 

 The second method given above has been developed by Lunddn 

 who determined the degree of hydrolysis of the salt of the acid 

 studied and of a weak base of a known dissociation constant.
