Recall that electrolytes are substances that conduct electricity in their aqueous or molten state, and get decomposed in the process. We are going to study the electrolysis of some electrolytes such as dilute tetraoxosulphate (VI) acid, dilute sodium chloride, concentrated sodium chloride, copper (II) tetraoxosulphate (VI) solution etc. Electrolysis of Acidified Water Using Platinum Electrodes The electrolysis of acidified water is carried out using the Hofmann voltameter . (Please click on the link or refer to your textbooks for a standard labelled diagram). Hofmann Voltameter Acidified water, which is simply dilute tetraoxosulphate (VI) acid, H2SO4, ionizes according to the equation:                                       H2SO4(aq) ----> 2H+(aq) + SO4--(aq) Meanwhile, the water molecules undergo partial dissociation to form H+ and OH-,                                      H2O(l) <----> H+(aq) + OH-(aq) Therefore, the acidified water contains three ion
