Match Column A with Column B:
Match Column A with Column B:
Show Hint
Solution and Explanation
(a) — 4. Redox: In this reaction, Copper Oxide is being reduced (loses oxygen) and Carbon is being oxidized (gains oxygen).
(b) — 3. Reduction: Gain of electrons is defined as reduction. Aluminum ions gain three electrons to form aluminum atoms.
(c) — 5. Electrolytic dissociation: The separation of ions of a pre-existing ionic compound (molten or aqueous) is called electrolytic dissociation.
(d) — 1. Oxidation: Loss of electrons is defined as oxidation. Oxide ions lose electrons at the anode to form oxygen gas.
(e) — 2. Ionization: The process by which a polar covalent compound (like gaseous HCl) forms ions when dissolved in water.
