Step 1
Step 2
Observations for zinc and copper
Answer
From the observations provided:
-
For zinc, bubbling was produced at a steady rate when it was added to dilute hydrochloric acid. This indicates a reaction was occurring, and hydrogen gas was likely being produced.
-
For copper, no reaction was observed, meaning copper does not react with dilute hydrochloric acid.
These observations indicate that zinc is more reactive than copper.
