Electricity

For assembling voltaic cells, electrolysis experiments etc.
Size (l x w), 125 x 25mm.

Size (l x w), 125 x 50mm with 4mm socket binding post terminal.

For electrolysis of reactive materials like hydrochloric acid and other compounds. Suitable alternative to platinum. Size (l x d), 150 X 5mm. Alligator clips can be used for making wire connections.

For measuring the quantity of electricity from the mass of copper deposited on one of its electrodes.
Consists of three copper plates suspended from a bakelite cover of a plastic jar. Outer two electrodes acting as double anode are connected to one binding post on the top. The third inner copper plate fixed to another binding post acts as a cathode and can easily be removed for weighing.

For qualitative and quantitative study of the electrolytic decomposition of electrolytes such as water, hydrochloric acid etc.
Consists of two vertical 50mL, gas-collecting, graduated glass tubes with stopcocks at top and joined by a bridging tube to a reservoir and fitted with a pair of platinum electrodes at the lower ends of the glass tubes. A lead wire connecting the platinum electrode passes through the glass tube for external connections, so that only the platinum electrode comes in contact with the electrolyte. Packed in a styrofoam case. Mounted on a cast iron stand designed for safe clamping. Requires a 6V battery or low voltage D.C. power supply for operation.

For use with Hoffman Electrolysis Apparatus described above 3155-01.

For use with Hoffman Electrolysis Apparatus described above. Size (l x d), 100 x 5mm. Inserted in a rubber stopper with insulated lead wire.
