The Daniell's cell consists of a copper plate c, dipping into a solution of copper sulphate contained in a glass, or glazed, highly vitrified stoneware jar, J, and a zinc plate, or rod, z, to which a copper wire, or strip, w, is soldered, dipping into either dilute sulphuric acid or a solution of zinc sidphafe, the two solutions being separated by a porous partition P, made of unglazed earthenware, and called a "porous pot". The E. M. F. of a Daniell's cell, and of all its modifications, is roughly 1.1 volts, but it varies from about 1.07 volts to 1.14 volts, depending on the densities of the solutions of copper and zinc sulphate.
Date 1891
