"Although copper can be separated from its solution by means of the electric current and the amount so separated varies directly as the current, there is a point in each and every solution where on account of the energy given off to the ions, the copper will be carried over in a more or less impure state, depending upon the strength of the current, the strength of the solution,whether it is saturated or only partly saturated, or whether normal basic or acid and also upon the amount of impurities in the solution. It is the purpose of this thesis (1) With a neutral solution of CuSO₄, varying in strength from a one-fourth saturated to a saturated solution, to find the strength of current at which the oxide of copper will be deposited on the cathodes. (2) With solution of same strength but varying the amount of H₂SO₄ from 1 to 10 cc, to find the strength of current necessary to deposit copper oxide. (III) To find the effect of lead, arsenic, antimony, bismuth and tin on the deposited copper"--Introduction, page 1.
