🧪 Examples of Reversible Reactions
- Copper sulfate hydration: CuSO₄·5H₂O(s) ⇌ CuSO₄(s) + 5H₂O(g)
- Ammonium chloride decomposition: NH₄Cl(s) ⇌ NH₃(g) + HCl(g)
- Haber process: N₂(g) + 3H₂(g) ⇌ 2NH₃(g)
- Thermal decomposition of limestone: CaCO₃(s) ⇌ CaO(s) + CO₂(g)
The copper sulfate hydration test is the classic example:
- Anhydrous CuSO₄ is white
- Hydrated CuSO₄·5H₂O is blue
- Adding water to white powder → turns blue + gets warm (exothermic)
- Heating blue crystals → turns white + steam released (endothermic)
- This test is used to detect the presence of water
