The black tarnish that forms on silver is silver sulfide, $\mathrm{Ag}_{2} \mathrm{~S}$. The tarnish can be removed by wrapping the silver with a piece of aluminum foil and placing it in a solution of $\mathrm{NaHCO}_{3}$ (baking soda) to allow for the flow of ions. Explain how the aluminum foil aids in removing the tarnish.
