  • Working Principle of Battery

    This type of simple cell can be created very easily. Take one container and fill it with diluted sulfuric acid as the electrolyte. Now immerse zinc and one copper rod in the solution and connect them externally by an electric load. Now your simple voltaic cell is completed. Current will start flowing through the external load.

  • John Daniell

    The amalgamated zinc rod (anode) had a binding screw. The top of the copper cylinder contained the other binding screw (hode). Daniell's last work on a gravity type of battery was later to become one of the most popular in the 1850's. He fused two electrolytes; copper sulfate (CuSO 4) and zinc sulfate (ZnSO 4 ).

  • Determination of iron (II) by permanganate titration

    As Fe 2+ gets easily oxidized by air oxygen, before titration we should ensure that all iron is in the form of Fe 2+. It is possible to reduce iron 3+ using Jones reductor (column filled with granules of amalgamated zinc), however, most commonly reduction is done with tin (II) chloride: 2FeCl 3 + SnCl 2 → 2FeCl 2 + SnCl 4

    To favor the desired reaction of xylose reduction, amalgamated zinc is used to perform the reduction in this study. The alytic amalgamated coating is formed by the electrodeposition of a zinc coating having desired properties on a copper mesh from a sulfate bath and its subsequent immersion into the HgCl2 solution to obtain.
