electrolytes are arranged vertically in the order of their effect on the 

 solubility of potassium bromate. Those values which appear in paren- 

 theses in the table are such in which interaction between the non-electro- 

 lyte and the electrolyte probably occurs. A negative value of the solu- 

 bility coefficient indicates an increase in the solubility. With the possible 

 exception of potassium bromate in the presence of glycocoll and potas- 

 sium perchlorate in the presence of formamide and urea, the increased 

 solubilities are probably to be ascribed to interaction between the elec- 

 trolyte and the non-electrolyte.
