Lessons in practical electricity; principles, experiments, and arithmetical problems, an elementary text-book . immediate use; on the copper side is placedsulphate of copper (CuS04), dissolved in water, together withsome sulphate of copper crystals (bluestone) to maintain thesupply of copper sulphate solution. When the circuit isclosed, as shown by Fig. 84, the zinc combines with the(S0+) of the sulphuric acid forming sulphate of zinc(ZnSO ), and thus sets free the two molecules of hydrogen(H2). 0 PRACTICAL ELECTRICITY. This hydrogen gas passes through the porous partition,but instead of collecting on the sides of the copper plate,it meets with the sulphate of copper (CuS04), and having agreater natural affinity for the (S04) than the copper (Cu)possesses, it displaces the copper, and forms sulphuric acid,(H2S04) setting free pure metallic copper, which is depositedupon the copper plate. This continuous extraction of metal-lic copper from the solution would soon weaken it, were itnot for the fact that the copper crystals dissolve and thusautomatically keep the solution saturated. To maintain a.
