Question- Tarnish on tin is the compound SnO. A tarnished tin plate is placed in an aluminum pan of boiling water. When enough salt is added so that the solution conducts electricity, the tarnish disappears.
Calculate the standard cell potential given the following standard reduction potentials:
Al3++3e??Al;E?=?1.66 V
Sn2++2e??Sn;E?=?0.140 V
