XVII. On the properties of electro-deposited antimony (concluded)

Abstract

92. In addition to the variety of electro-deposited antimony obtained from a solution of teroxide of antimony and hydrochloric acid, a second variety may be obtained from a solution of terbromide of antimony in the following manner. 93. Dissolve one part of teroxide of antimony in 10 parts of hydrobromic acid of sp. gr. about 1⋅3, filter the solution through a funnel loosely plugged with asbestus, and electrolyse it by means of three Smee’s elements and an anode of antimony in the usual manner, at a speed of deposition of about 3 to 5 grains per square inch per hour. The exact proportion of the ingredients of the solution is not a matter of great importance.
