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.
