1. 35. EOY - Electrolysis 2 [2021]
ELECTROLYTIC CELLS (IMPORTANT POINTERS) 1. inert electrode: graphite (C) / Pt, reactive electrode: other metals 2. inert & reactive cathode: choose cations (lower in reactivity series), inert anode: choose anions (take note of concentration effect), reactive anode: dissolve 3. replenishing effect exists if anode and cathode reactions are opposites of one another 4. electroplating requires cathode to be object, anode to be same metal to be plated, electrolyte contains cation to be deposited
