Inquiry in Action! (Individual): In this activity, answer the questions to be able to apply it in such scenario. In one episode of the TV sitcom, Gilligan's Island, the “professor" constructed voltaic cells to use as substitutes for their radio's dead batteries. Which scraps of metal from their damaged boat, the Minnow, could best be used to create a 1.5 V voltaic cell? Explain further to support your answer (Assume that coconuts make great beakers, and that seawater is a terrific electrolyte!) Metal/Metal ion lead/lead (II) (fishing weights) iron/iron (II) (the anchor) silver/silver(I) (Mrs. Howell's brooch) aluminum/aluminum(III) (the boat's flagpole) E -0.126 -0.44 -0.799 -1.677

Batteries

A battery is simply an electrochemical cell or group of cells that generate electric current. Batteries are the devices that generate current using redox reactions. These reactions proceed by the transfer of electrons. An ideal battery or cell should produce a constant voltage. A battery should actually be light in weight.
