MCQ
Which of these metals do not corrode?
- ALead
- BCopper
- CPlatinum
- DSilver
✓
Answer
- Platinum
Explanation:
Corrosion is a process through which metals in manufactured states return to their natural oxidation states. This process is a reduction-oxidation reaction in which the metal is being oxidized by its surroundings, often the oxygen in air. As platinum is least reactive so it will not corrode.
