LECLANCHE CELL
T1978.221
In this cell, known by the name of the physicist who devised it, the materials are zinc, carbon, and a concentrated solution of ammonium chloride (sal-ammoniac). Manganese dioxide is used as a depolarising agent. The zinc rod Z dips into the solution of sal-ammoniac contained in the glass jar. When the cell is in action, ammonia and hydrogen are produced; the ammonia gas , being very soluble in water, does not tend to produce polarisation. The manganese dioxide is but a very slow oxidising agent, and the cell consequently soon becomes polarised if used continuously; it soon becomes depolarised, however, if allowed to remain unused for a short time.
