Potassium Phenate. 



Carbolic acid or phenol is another well-known weak acid 

 which forms a crystalline salt with potash. As an experi- 

 ment with this salt seemed likely to be interesting, solutions 

 of it were prepared by mixing equivalent quantities of solu- 

 tions of potash and phenol of known strength and then diluting 

 until solutions of the salt of the required concentration were 

 obtained. Two sets of experiments were made ; one with
