Use this apparatus for qualitative and quantitative study of the electrolytic decomposition of electrolytes such as water, Hydrochloric acid, etc. It consists of 2 vertical 50ml gas-collecting, graduated glass tubes with stopcocks at top. The tubes are joined to a reservoir by a bridging tube and fitted with a pair of platinum electrodes at their lower ends. 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. The apparatus is mounted on a cast iron stand. Comes with a Teacher’s Guide and reproducible student handout.

*Requires a 6V battery or low voltage DC power supply for operation (NOT INCLUDED)*
