Question

With diagram, discuss the siemen's ozoniser method of preparation of ozone.

Accepted Answer

Ozone is obtained when silent electric discharge is passed through pure, cold and dry dioxygen in a specially designed apparatus called ozoniser. The types are Siemen's ozoniser and Brodie's ozoniser, Siemen's Halske ozoniser.

It consists of two co-axial glass tubes fused together. Tin foil is used to coat the inner-side of the inner tube and the outer-side of the outer tube. The inner and outer tin coatings are connected to the terminals of an induction coil, which produces current of high voltage. A slow current of pure and dry oxygen is passed through the annular space. On subjecting oxygen to silent electrical discharge, ozonised oxygen containing 10-15% ozone is formed.
