Caption: Daniell Cell. This is an electrochemical cell invented by John Daniell in 1836. It consists of a copper cathode (often a copper pot) filled with copper sulphate solution. Inside this sits an unglazed earthenware pot containing a zinc anode and zinc sulphate solution. The zinc is oxidised at the anode, the copper reduced at the cathode, with the overall equation Cu2+ + Zn => Cu + Zn2+, generating an open circuit voltage of 1.1018 Volts.
