Table 283. 



ELECTROCHEMICAL EQUIVALENTS. 



With the exception of the values in hea\'\- type for copper and silver, the numbers in this table have been calculated 

 from the atomic weights and valence, on the basis of the value given for silver which was adopted by the Inter- 

 national Congress of Electricians at Chicago in 1894. Many of the substances have not been separated electri- 

 cally, and in these cases the numbers are purely theoretical. 



* The atomic weights are from a paper by F. W. Clarke. " Journ. Am. Chem. Soc." vol. 18, p. 213, 1896.
