Chloride ions are added to the AglAg* half-cell of the cell Ag|Ag*l|Cu²*|Cu to precipitate AgCI (s). The cell voltage is then measured to be +0.072 V at 298 K. If [Cu2+] = 1.0 M in the Cu2+|Cu half cell, what is [Ag*] in the Ag|Ag* half-cell? (First step: You will need to use the data in Table 17-1 to calculate E°cell.) Give your answer to two significant figures. Ecell = E°cell - (0.0257 V/n) In(Q) E'cell = E°ox + E°red
