The increase of the cathode efficiency with the concentration of the non-electrolyte up to the limiting value has been attributed to the decreasing solvent action of the bath solution over the deposited copper. [...] 1916 38 1156) from the coparison of the copper cottlometers containing varying quantities of cane sugar and of tartaric acid with silver coulometers came to the conclusion that the mass of the deposit increases to a limiting value with the increasing content of the addition agent and is by no means restricted to the case of gelatin. [...] The addition of non-electrolytes however alters the condition of the bath and brings about the diminution in the concentration of the copper ions in the solution thus lowering the solvent effect. [...] In the presence of large excess of these noelectrolytes due to limited solubility of the electrolyte in the medium it is possible to imagine a stage of supersaturation or even actual separation of the salt a stage which was actually realised especially in the presence of zo% non-electrolyte as mentioned in the foot notes in Tables II and III The separation of the salt naturally alters th [...] The following experiments were carried out in order to investigate the utilisability of dilute silver nitrate solutions in respect of the following factors : r. The optimum conditions for the production of a smooth and aherent deposit of silver at various values of the duration of the electrolysis the inter-electrode distance the electrolyte concentration temperature and current.
