You're given beakers, wires, a voltmeter, strips of tin, strips of silver, and a bottle of AgNO3 and a bottle of SnSO4 in order to determine experimentally if Equation: Sn(s) + Ag+(aq) -> Ag(s) + Sn2+ (aq) is spontaneous or not. Describe or draw with a picture how you would set up the Equation reaction.
One useful method for recycling scrap aluminum converts some of it to common alum [potassium aluminum sulfate dodecahydrate, KAl(SO4)212 H2O], an important dye fixative and food preservative.
