Hoffman Electrolysis Apparatus

For qualitative and quantitative study of the electrolytic decomposition of electrolytes such as water, hydrochloric acid etc.

Description

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.
