To quickly assess the difficulty of the text, read a short excerpt:
Is used, ahout 3 volts being required with a current of 12 to 15 amperes per square foot of work surface, the density of the solution being about 20 deg. Baume, although a higher voltage can be used if it is desired to shorten the time of deposit. For mechanical apparatus, where the revolving container is used, the solution is brought to a density of 25 to 30 deg. Baume and 8 to 10 volts are used with a corre- sponding increase in current. The following zinc solutions have also been used satisf...actorily on different classes of work and under varying condition. They are given here so the user of the book may have a basis on which to work in experimenting to find the solutions best suited to his apparatus and work: Formula 3 Zinc sulphate '. . -4-4 Ihs. Pure crystallized sodium sulphate 8. 8 Ibs. Chemically pure zinc chloride 2. 2 Ibs. Crystallized boric acid 1. 1 H>s. Water 25 gals. Worn/into. -4 Zinc sulphate 50 Ibs. Ammonium chloride 3. 1 Ibs. Aluminum sulphate 0. 2 Ibs. Water 25 gals.
