A student wishes to determine the chloride ion concentration in a water sample at 25 \deg C using a galvanic cell constructed with a graphite electrode and a half-cell of AgCl(s) + e > Ag O + Cl(aq) E\deg red = 0.2223 V And a copper electrode with 0.500 M Cu^2* as the second half cell Cu^2+ (aq) + 2 e > Cu(s) E\deg red= 0.337 V The measured cell potential when th water sample was placed into the silver side of the cell was 0.0781 V. Given the standard cell potential for this cell is 0.115 V, and the measured cell potential is 0.0781, what is the concentration chloride ions in the solution?
