Hofmann Voltameter with Large Platinum Electrodes – It consists of three joined upright glass cylinders.

Hofmann Voltameter – with Large Platinum Electrodes – It consists of three joined upright glass cylinders. One cylinder is open at the top to allow addition of water and an ionic compound to improve conductivity, such as a small amount of sulphuric or hydrochloric acid. A platinum electrode is placed inside the bottom of each of the two other cylinders, connected to the positive and negative terminals of a source of electricity. When current is run through Hofmann’s voltameter, gaseous oxygen forms at the anode and gaseous hydrogen at the cathode. Each gas displaces water and collects at the top of the two outer tubes.

Electrodes have large surface area for fast reaction/result.
Will operate with Solar Cell for powerful demonstration.
Spares available. Very popular.
