Fig. 5. Conductivity of inverting solution. 



Summary of Results. 



The measurement of conductivity affords a delicate method of 

 tracing the course of certain reactions. 



In the case of the action of water on monochloracetic acid, the 

 action as a whole proceeds as a monomolecular reaction, but there 

 is a period of induction. 



This induction period may be explained by assuming that the 

 first stage of the action is the formation of an additive compound 

 of a water molecule and a monochloracetic acid molecule, this 

 additive compound then breaking down yielding a molecule of 

 glycollic acid and hydrochloric acid.
