Question

Write a conversation between the electrodes and the electrolyte during electrolysis to justify your choice of materials anode- Zinc sulphate cathode- aluminum strip

Answer 1

Oxygen is produced (from hydroxide ions), unless halide ions (chloride, bromide or iodide ions) are present. In that case, the negatively charged halide ions lose electrons and form the corresponding halogen (chlorine, bromine or iodine).
