Part A through H
1. [60 pts) A galvanic cell is a type of battery where the electrodes are immersed in different electrolyte solutions, which are connected by an ion-conducting bridge. Consider a galvanic cell with Al and Cu electrodes. The Al electrode is immersed in a solution containing a standard concentration of Al3+ ions and the Cu electrode is immersed in a solution containing a standard concentration of Cu* ions. External Circuit The standard reduction potentials for the half...

2. Consider the voltaic cell illustrated below, constructed by coupling a Ni/Ni half-cell with an Ag/Ag* half-cell and allowing them to react spontaneously. Refer to the table of reduction potentials and write the half-reaction that occurs at each electrode (nickel and silver). Then combine the half-reactions into the overall reaction. a. Calculate the standard cell potential. b. Annotate the diagram below. First, randomly label one electrode as Ag and one as Ni. Then identify which is the anode and which...

Remember that the current coming into a junction equals the current coming out of the junction. Also bear in mind that voltage is basically a height difference between two points. 1) If you measure the potential across two batteries and find that V1 = 1.3V and V2 = 1.4V, then you measure the potential between the negative ends of battery 1 and positive end of battery 2 and get V12-+ = -0.1 and the potential between the positive ends of...
