The following conclusions may be drawn from the above tables : 



I. In general, the molecular conductivity of a salt increases with increasing 



dilution. 



II. The oxysalts of all alkali metals behave differently to the haloid salts.* 

 III. At all concentrations investigated, the conducting power of the oxysalts of 

 any one metal is approximately the same. 



With regard to the halogen salts, it appears that potassium iodide occupies an 

 intermediate position, forming a transition member from the haloids to the oxysalts. 

 Sodium bromide and iodide would appear to occupy a similar position among the 

 sodium salts. 



It appears also that with increasing concentration the molecular conductivity of the 

 oxysalts attains a minimum value. This is very evident with the oxysalts of potas- 

 sium, and recognisable in those of rubidium and csesium, the minimum values being 

 11, 26, and 34 in the respective cases. 



* Potassium chlorate, being converted by the flame into the chloride, is an exception to this statement.
