You are on your dream vacation at the beach when a major storm knocks out the power for days. Your cell phone is dead, and you want to make a battery to charge it. You find the following materials in the beach house. blue Stone algaecide for pools, which can be used to make a 1.0 M Cu 2+ solution alum in the kitchen, which can be used to make a 1.0 M Al 3+ solution aluminum foil, copper wire, and bologna, which can be used as a salt bridge (a) What are the half reactions and overall reaction in the battery? (b) What voltage can be generated? (c) Draw a diagram using beakers, a voItmeter, and salt bridge to show how a battery can be constructed. Label the anode, cathode, and direction of electron flow. (d) An iPhone requires 5.0 V for charging. Can this battery charge the phone? Explain.
