What is the concentration of chloride ions (Cl-) in a water sample if the measured potential difference is -0.45V using a silver/silver-chloride (Ag/AgCl) electrode? The standard electrode potential for the half-cell reaction AgCl(s) + e- → Ag(s) + Cl-(aq) is 0.222V. The temperature of the sample is 25°C and the ionic strength is 0.1M.

What is the concentration of chloride ions (Cl-) in a 500 mL solution if the potential difference between the reference electrode and the indicator electrode is measured at 0.84 V using a silver-silver chloride electrode? The sample contains an unknown amount of chloride ions and was titrated with a standard solution of silver ions (Ag+) until the equivalence point was reached. The titrant used in the experiment had a concentration of 0.1 M.
