A voltaic cell utilizes the following reaction:Al(s) + 3 Ag+(aq)--->Al3+(aq) + 3 Ag(s) What is the effect on the cell emf of each of the followingchanges? (a) Water is added to the anode half-cell, dilutingthe solution. (b) The size of the aluminum electrode isincreased. (c) A solution of AgNO3 is added to the cathodehalf-cell, increasing the quantity of Ag+ but not changingits concentration. (d) HCl is added to the AgNO3 solution,precipitating some of the Ag+ as AgCl.
