Table I comprises 28 columns and extends across two facing pages. The division between facing pages is very nearly such that the left-hand pages identify the compounds for which data are giver., the technique by which the data were obtained, and the electrodes used, and also describe the solvent and supporting electrolyte, apparatus, and experimental conditions, while the right-hand pages give the data and other information obtained and provide cross-references to additional information contained in other tables.

Example. 25 g Tropinone are solved with 11 g of concentrated sulfuric acid in water in 180 ccm and brought into the cathode area of a Electrolytic apparatus separated by a diaphragm, in whose anode region one is approximately in the concentration 1 10 diluted sulfuric acid. As electrodes appropriate lead sheets serve. One electrode with a current density of 1.2 Amp./qdm with 3.5 to 4 V, however also higher and low current densities and tensions are usable. A hydrogen development arises at the cathode only after passage of the Amp. hours theoretically necessary for the reduction of the tropinone. After termination of the reduction, pseudotropine is isolated in the way described above. Source Merck 1900... [Pg.152]

Suppose that you need a coating of rhodium (a precious metal) on a part that is to be used as a mirror in a laser. Because rhodium is so expensive, you wish to deposit only 4.5 mg on the surface of the part. If you run an electrolytic apparatus for 5.0 min, what current do you need to deposit the desired amount from a solution containing Rh ions ... [Pg.564]
