Silver Teaspoon
Removing Tarnish from Metal?
Quick discription of the experiment:
Anyway, this can be replicated in the home by taking a glass dish, putting a piece of heavy aluminum foil in the bottom, then filling the dish with hot tap water and adding a teaspoon of baking soda. Stir well, and place the silver object in the solution, making sure that the object touches the aluminum foil at the bottom. After several minutes, remove the silver item from the pan and rinse with water. You find out that the tarnish disappears. The process can be repeated if the tarnish is heavy.
Questions:
3. Why was it necessary to heat the water that you mixed with the baking soda?
4. Why was aluminum foil used instead of another metal?
6. In the space below, type the redox half-reaction for the chemical reaction. Identify which material is oxidized, and which is reduced.
Heat the water to increase the rate of the reaction
Aluminum foil was chosen for it’s electronegativity; you’re creating an aluminum-silver battery.
roughly
Al + AuOn -> AlOn + Au
The silver has already oxidized (tarnished) so it must now be reduced.
Hence,it is the aluminum that is being oxidized.
