The other electrode is a platinum or lead orsilver plate of much larger surface, and the two are immersed in anelectrolyte, which may be nitric acid, dilute sulphuric acid, or anyother aqueous electrolyte yielding oxygen or hydrogen on electro-lysis (see Fig. 15). The electrode of small surface is generallyprepared from a Wollaston wire by drawing down a platinumwire coated with silver, or else a platinum wire coated with iron,until the platinum wire itself is less than 0-001 mm. in short length of the compound wire is then fixed to the end of ascrew, so that it can be lowered by a very small amount into theelectrolyte. If, for instance, the electrolyte is nitric acid, then asilver-coated wire is employed, and on lowering the tip of this into.
