Content
Electrolysis of acidified water
The electrolyte is dilute sulfuric acid (acidified water) which, during electrolysis is split into hydrogen and oxygen gases. Theoretically into a 2:1 ratio by gas volume.
This is one experimental method of showing water is a compound composed of the elements hydrogen and oxygen atoms i.e. by splitting liquid water into two gaseous element molecules of hydrogen (H2) and oxygen (O2).
Water only ionises to a tiny extent giving minute concentrations.... View More
