... The conductance of a solution is measured by dipping a cell containing two platinum electrodes into the solution. The electrodes are connected to one arm of a Wheatstone bridge and an alternating voltage is applied to the bridge. The conductance is then obtained from the scale by nulling the bridge. ...

Electrolysis of water
Electrolysis of water is the decomposition of water (H2O) into oxygen (O2) and hydrogen gas (H2) due to an electric current being passed through the water.This technique can be used to make hydrogen fuel (hydrogen gas) and breathable oxygen; though currently most industrial methods make hydrogen fuel from natural gas instead.
