प्रश्न
Write scientific reason.
Adding zinc particles to a solution of copper sulphate makes the blue solution colorless.
उत्तर
- Zinc is more reactive than copper.
- Therefore, zinc displaces copper from copper sulphate solution.
- The blue colour of copper sulphate solution fades due to the formation of colourless zinc sulphate.
Hence, adding zinc particles to a solution of copper sulphate makes the blue solution colorless.
