 VOLTAMETER, COPPER

 

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.

 HOFFMAN ELECTROLYSIS APPARATUS

 

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.
