XII—The Absorption of Light by Inorganic Salts. No. IX.: Solutions of Copper, Nickel, and Cobalt Salts in Alcohol and in Acetone

Abstract

The absorption spectra of the copper, nickel, and cobalt salts investigated in this series do not seem to depend so much upon the acid radical as on the water of solution. The latter evidently plays a very important role, and possibly complicates matters. It was therefore resolved to determine the molecular extinction coefficients in alcohol and in acetone to see whether conditions were any simpler there. It may be stated in advance that they are not.
