Meaning and terminologies used in electrolysis
Answer Text: ELECTROLYSISDefinition-Is the decomposition of molten or aqueous solutions by passage of electric current through it.Terminologies used inelectrolysis:i) Electrolyte- Is a solution which allows electric current to pass through while it gets decomposed.- Electric current transfer in electrolyte occur through ions.- The electrolyte can be aqueous solutions or molten solutions- Electrolyte with may ions are called strong electrolyte; while those with few ions are called weak electrolytes.Examplesii) Electrodes - Are the solid conductors, usually roots, which usually complete the circuit between electrolytes and cell/battery- Are of two typesa) Anode - The electrode connected to the positive terminal f a battery/cellb) Cathode- Electrode connected to the negative terminal of the battery/cell.Note: Graphite rods are commonly preferred as electrodes in most access.Reasons: They are inert/unreactive -Are cheap- Platinum is also relatively inert; but not less preferred to Graphite because its expensive.
