Daniell Cell. This is an electrochemical cell invented by John Daniell in 1836. It consists of a beaker containing a copper cathode immersed in copper sulphate solution,and another beaker with a zinc anode immersed in zinc sulphate solution. The two beakers are connected by a salt bridge (a tube filled with potassium nitrate in an agar gel matrix). 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 | |
