Effect of Salt and Boiling Water on Platinum in Tin Foil

1. Under certain conditions, tin foil (aluminum foil), salt (sodium chloride) and boiled water (water) may react with platinum, resulting in changes in the surface of platinum.

2. When tin foil, salt and boiled water are mixed together, substances such as aluminum chloride (AlCl3) and sodium hydroxide (NaOH) will be produced. Aluminum chloride is a colorless to yellowish crystal with strong hygroscopicity. Sodium hydroxide is a white solid, soluble in water and alkali.

3. Platinum is a precious metal with stable chemical properties and strong corrosion resistance. At room temperature, the mixture of platinum and tin foil, salt and boiling water may have no obvious chemical reaction.

4. However, in the case of high temperature or long-term contact, the surface of platinum may be affected to some extent, such as surface oxidation and discoloration.
