Скачать или смотреть Displacement Reaction | How Iron Replaces Copper

In this experiment, students demonstrate a single displacement reaction using copper sulfate solution (CuSO₄) and iron nails. When iron is placed in the blue CuSO₄ solution, iron atoms go into the solution as Fe²⁺ ions, while copper ions (Cu²⁺) are reduced and deposited as a reddish-brown layer on the surface of the iron nails. The blue color of the solution gradually fades as copper ions are replaced by iron ions. This reaction occurs because iron is more reactive than copper in the metal activity series.

Learning Outcomes:
1. Understand the concept of single displacement reactions in inorganic chemistry.
2. Observe how more reactive metals displace less reactive metals from their salts.
3. Identify the visible signs of a chemical change (color fading, copper deposit).
4. Learn how the reactivity series predicts reaction outcomes.
5. Connect the experiment to practical applications like metal extraction and corrosion.

This experiment was performed by students as part of an exploratory chemistry activity.
