Not illustrated. 1888 edition. Excerpt: ...a small quantity of sulphate of copper, and a large quantity of sulphate of zinc, in a large quantity of water, and pass a strong current through the solution, copper, zinc, and hydrogen will be set free at the cathode. 3rd. If we slightly moisten a lump of caustic potash with pure water, and pass a weak electric current through it by platinum electrodes, hydrogen alone will be set free at the cathode, but if a very powerful current is employed, potassium also will be deposited. In each of these cases we find that when the current is weak the least positive of the positive substances is alone deposited; but if the power is sufficiently increased, and there is only a small proportion of the less positive substance present, the more positive substances, even though they are much more positive, will also be liberated. Thus the weaker affinities are overcome first, and to the greatest extent; the current of electricity exercising its influence first, and in the greatest proportions, upon the salt of the least positive metals. 96. Depositing Liquids.--For the benefit of the practical depositor--to whom a general knowledge of all solutions from which ordinary metals may be deposited, with their respective advantages and disadvantages, is of considerable importance--we will give a description of those solutions in regular order, making such remarks in our progress as will be likely to assist him in the selection of those most suitable for his particular purposes. 97. Antimony Solutions.--The most common salts of antimony are the sulphide, terchloride, and potassio-tartrate. The hydrochlorate of terchloride of antimony, i.e., the ordinary chloride of antimony, as prepared for pharmaceutical purposes, is formed by chemical means thus:--Take one...
