Question
Explain why metals like zinc can displace hydrogen from dilute acids, while metals like copper cannot. Use the reactivity series in your explanation.
Answer
Zinc is more reactive than hydrogen, which allows it to displace hydrogen from dilute acids, forming zinc chloride and hydrogen gas. In contrast, copper is less reactive than hydrogen, so it cannot displace hydrogen from dilute acids.
Explanation
This question assesses the student's ability to apply knowledge of the reactivity series to explain displacement reactions. It requires understanding the relative reactivity of metals and their ability to react with acids.
Common mistake
Confusing Metal Reactivity
Students often think that all metals react with dilute acids in the same way, not considering their reactivity.
Students should remember that the reactivity of metals varies, and only certain metals react vigorously with dilute acids, while others may not react at all.
