Text Solution

AI Generated Solution

To answer the question "Why does copper not replace hydrogen from acids?", we can break down the explanation into clear steps: ### Step-by-Step Solution: 1. **Understanding Electrode Potential (E0)**: - Electrode potential (E0) is a measure of the tendency of a chemical species to be reduced, which reflects its reactivity. A positive E0 value indicates that the element is less likely to lose electrons and thus is less reactive. 2. **Copper's Electrode Potential**: ...
