Tin crystals are easy to grow, using a simple displacement chemical reaction: Sn2+ + Fe --> Sn + Fe2+
Difficulty: Easy
Time Required: an hour to overnight
Here's How:
- Suspend the iron wire or nail in a test tube containing tin chloride.
- After about an hour, crystals will start to form. You can examine these with a magnifying glass or by removing the wire and looking at the crystals under a microscope.
- Allow the iron to remain in the solution overnight for more/larger crystals.
What You Need:
- iron wire or nail
- 0.1 M tin chloride
- test tube
