A solution prepared by mixing 16.7 mL of 0.760 M NaCl and 16.7 mL of 0.760 M KI was titrated with 0.380 M AgNO3 in a cell containing a silver indicator electrode and a saturated calomel reference electrode.
(a) What is [Ag+] when 16.2 mL of 0.380 M AgNO3 have been added? Express your answer as x, where [Ag+] is a quotient having the form Ksp,AgI/x.
(b) What is [Ag+] when 48.0 mL of 0.380 M AgNO3 have been added? Express your answer as y, where [Ag+] is a quotient having the form Ksp,AgCl/y.
d)The difference between voltages measured when 48.0 mL and 16.2 mL of AgNO3 have been added is 0.3857 V. Using this voltage difference and your answers to questions (a), (b), and (c), calculate the numerical value of the quotient Ksp,AgCl/Ksp,AgI.
**answer to C was E = ( 0.799 - 0.05916log(1/[Ag+]) ) - 0.241**
