TABLE III. 



The quaternary system : Cu SO4 — Cu CI. — K. SO4 — K. Clo - Ho at 30°. 



Ions Cu, Ko SO4 and CL and Mol. H^ in a quantity of 



solution which contains 100 Mol. in all. 



In table III the compositions are indicated in the nnmber of ions 

 Cn, K2, SO4 and CI, and molecnles H^O, which are present in a 

 quantity of solution, which contains in all 100 molecules. 



When a solution contains a ions Cu, 6 ions K^, c ions SO^, r/ions CI3 

 and w molecules of water, then is consequently
