A student places strips of zinc and tin into separate test-tubes containing aqueous copper(II) sulfate. After a few minutes, only the test-tube with zinc shows a brown solid forming and the blue solution fading. What does this show about the relative reactivity of zinc, tin and copper?
- Zinc is more reactive than copper, which is more reactive than tin
- Tin is more reactive than zinc, which is more reactive than copper
- Copper is more reactive than zinc, which is more reactive than tin
- Tin is more reactive than copper, which is more reactive than zinc
