  EXERCISE 2.2 CHEMISTRY FOR ENGINEERS ELECTROCHEMISTRY Pr actice Exercise 7. Calculate the cell potential for a galvanic cell in which the following reactions take place:              2Al    +    3Pb 2+ (0.1M)   ®   2Al 3+ (0.01M)   +    3Pb Practice Exercise 8.   A galvanic cell is constructed from a silver half-cell and a copper half-cell. The copper half-cell contains 0.10M Cu(NO 3 ) 2 and the concentration of silver ions in the other half-cell is unknown. If the silver electrode is the cathode and the cell emf is measured and found to be 0.10 v at 25 o C, what is the Ag + ion concentration?
