d there is no polarization. In orderto maintain the copper sulphate solution of constant strengthcrystals of sulphate of copper are placed in the solution, usuallyin a small tray at the top of the cell, these are graduallydissolved, thus replacing the copper deposited on the copperplate. The… … Fig. 129. 204 ELECTRICITY [CH. XIII Sometimes the cell is made up with a concentrated solutionof zinc sulphate in water, instearl of the sulphuric acid. Theelectromotive force depends on the solution, and varies fromabout 1-18 volts when sulphuric acid diluted with twelve partsof water is used, to…
