8 THE MANTJFACTUEE OF CHEMICALS BY ELECTROLYSIS that of 20-30 per cent, sulphuric acid, but it has the great advantage that it is without corrosive action on iron, and therefore plant can be constructed of iron or steel with electrodes of the same material "when an alkaline liquid is employed. Moreover, when lead is used for the electrodes, as it must be with a sulphuric acid electrolyte, considerable over- voltage occurs at the electrodes; hence, in spite of increased conductivity the economy in energy is negligibly small. Great difficulty has been experienced by all inventors in constructing a cell which will effectually prevent any mixing of the gases evolved and the formation of a danger- ously explosive mixture. This point, it will be observed, receives special attention in all the cells described. 1 SCHOOP'S PLANT. In this cell dilute sulphuric acid is employed, and the electrodes, as well as the containing vessel,are constructed of lead. Bach electrode is encased in an earthenware tube which is perforated round its lower portion, and sealed at the top with insulating material. Each electrode is thus completely separated from the rest, %nd intermixture of the gases is rendered impossible. Dilute sulphuric acid (density 1*235) is the electrolyte employed, and the voltage required for each unit is about 3'9 volts. The diagram (Fig. 4), which shows a section through two cells, will explain the construction. Each unit consists of a lead-lined vat which contains 1 J. Soc.Chem.
