Chemistry Science Investigation B Townend 10R 28/06/01 Electrolysis Plan Scientific Knowledge Most inorganic and some organic chemical compounds, when in a molten state or when dissolved in water or other liquids, become ionised; that is, their molecules become dissociated into positively and negatively charged components, which have the property of conducting an electric current. If a pair of electrodes is placed in a solution of an electrolyte, or an ionisable compound, and a source of direct current is connected between them, the positive ions in the solution move toward the negative electrode and the negative ions toward the positive. On reaching the electrodes, the ions may gain or lose electrons and be transformed into neutral atoms (those with a full outer shell) or molecules, the nature of the electrode reactions depending on the potential difference, or voltage, applied. The action of a current on an electrolyte can be understood from a simple example....
