It is desired to neutralize a solution X that contains a mixture of potassium chloride and hydriodic acid. Titration of 11.9 mL X with 0.134 M silver nitrate required 49.9 mL of the latter. The resulting precipitate, containing a mixture of AgCl and AgI, was dried and found to weigh 1.430 g. How much 0.102 M sodium hydroxide should be used to neutralize 11.9 mL solution X?
