Anodizing is a process of electrolysis. The anode used is an aluminium plate, and any common cathode can be used (usually aluminium is also used as the cathode). The electrolyte is dilute sulphuric acid. When electric current is passed through the electrolytic cell for some time, a layer of aluminum oxide is formed. The process is called anodizing of aluminium (the aluminium plate).
After anodizing, the aluminium oxide layer can be made closely-packed by putting the aluminium plate in water and heat the water to boil. If a dye is dissolved in the water, the aluminium plate will become coloured.
Ionization is process of formation of ions from electrically neutral species.
CH3COOH(aq) = CH3COO^-(aq) + H^+(aq)
HCl(g) + aq → H^+(aq) + Cl^-(aq)
