ResumoFour copper cells separating two silver cells were run in series. The areas of the four copper cathodes increased from 10 to 50 s.cs. By plotting the weights of the copper deposits against the corresponding areas of the cathodes, and extrapolating to zero area, the weight of the deposit is corrected for under experimental conditions. The atomic weight of copper = corrected weight of Cu/mean weight of Ag × 107.88 × 2. The mean atomic weight for 10 determinations = 63.563, with a mean error of ±003. To obtain a uniform coherent deposit of pure metal the following points were considered: -
