The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Reaction**: The question states whether copper reacts with dilute hydrochloric acid to liberate hydrogen gas. To analyze this, we need to understand the general behavior of metals with acids. 2. **Reactivity Series**: In the reactivity series of metals, metals that are more reactive than hydrogen can displace hydrogen from acids. For example, metals like zinc and magnesium can react with dilute hydrochloric acid to liberate hydrogen gas. 3. **Examining Copper**: Copper is a metal, but it is less reactive than hydrogen. This means that copper cannot displace hydrogen from dilute hydrochloric acid. 4. **Expected Reaction**: If copper were to react with dilute hydrochloric acid, we would expect a reaction that produces copper chloride (CuCl2) and hydrogen gas (H2). However, since copper is less reactive than hydrogen, this reaction does not occur. 5. **Conclusion**: Since copper does not react with dilute hydrochloric acid to liberate hydrogen gas, the statement is **False**. **Final Answer**: False ---
