Cambridge Secondary (7-9). Stage 9. MCE Science. Workbook - Unit 6: Displacement Reactions - Question 10

In this investigation, clean a small piece of zinc and a copper wire with sandpaper to remove oxide layers. Put zinc in test tube A and copper in test tube B; each contains 10 cm³ of dilute hydrochloric acid. Wear safety goggles and work in groups.

Based on your understanding of the reactivity series, which metal do you think will react with dilute hydrochloric acid? State a hypothesis.
