Excerpt from Electro-Analysis Many chemical compounds are decomposed when exposed to the action of an electric current. Such a decomposition is called Electrolysis. The substance decomposed is termed an electrolyte. The products of the decomposition are the anions and cations, or those (i) which separate at the anode, the positive electrode or pole and (2) those separating at the cathode, the negative electrode or pole - P) of the source of the electric energy. This behavior of compounds has become of great service to the analyst, inasmuch as it has enabled him to effect the isolation of metals from their solutions, and by carefully studying the electrolytic behavior of salts it has been possible for him to bring about quantitative determinations and separations. This method of analysis - analysis by electrolysis - has been designated electro - chemical analysis or, better, Electro analysis. It is especially inviting, Since it permits of clean, accurate and rapid determinations where the ordinary meth ods yield unsatisfactory results. This statement will at once be confirmed on recalling the gravimetric methods usually employed in the estimation of copper, mercury, cadmium bismuth, tin, or almost any metal.
