The anode of a dry cell is made up of - (1) Iron (2) Cadmium (3) Zine (4) Lead
by

1 Answer

Answer :

(3) Zine Explanation: A standard dry cell comprises a zinc anode (negative pole), usually in the form of a cylindrical pot, with a carbon cathode (positive Pole) in the form of a central rod. The electrolyte is ammonium chloride in the form of a paste next to file zinc anode. The remaining space between the electrolyte and carbon etthode is taken up bye. second paste consisting of amoniumm chloride and manganese dioxide, the latter acting as a depolariser.

(3) made cathode and a pure nickel red, the anode Explanation: Electroplating is the deposition by electrolysis of a coating of metal upon a conducting surface. The simplest system makes the object to be plated the negative electrode (cathode) or plate in a galvanic couple. Thus a spoon or other object may be connected by a wire to a plate of nickel. The process that occurs on the spoon is called reduction and, therefore, the spoon is also referred to as a cathode.
