Step-by-step explanation:
Electrolysis of acidified water
Water is a poor conductor of electricity, but it does contain some hydrogen ions, H+, and hydroxide ions, OH-. These ions are formed when a small proportion of water molecules naturally dissociate. If water is acidified with a little dilute sulfuric acid:
H+ ions are attracted to the cathode, gain electrons and form hydrogen gas
OH- ions are attracted to the anode, lose electrons and form oxygen gas
The overall balanced equation for the process is: 2H2O(l) → 2H2(g) + O2(g)
The volume of hydrogen given off is twice the volume of oxygen given off.
