The Electrolytic Preparation of Amalgams.

Abstract

influence the relation between the degrees of dissociation of the zinc and the nickel salts respectively. Accordingly, two solutions were prepared, both fairly dilute, and differing not too extensively in the relative concentrations of the nickel and the zinc salts. T h e data for these solutions are :-(a) Solution same as for Series 4, except that the total volume of the solution is fifteen liters (i.e. three times as much as before). Witb current densities above two amperes the alloys obtained were practically of constant composition. T h e alloy obtained with C.D. = 3 amp. contained 4.6 per cent. nickel. Hence the ratio of zinc to nickel (by equivalents) in the alloy equals 5.4 times their ratio in the electrolyte.
