e) via:. Lisbeth Myla CHEM 3321 A Back titration - Homework A solution containing Cl- was analyzed as follows in a back titration. A solution containing (excess) Ag + is added, and the AgCl precipitate is filtered and removed. The excess Ag is then titrated with SCN- Ag+ (aq) + Cl(aq) - Ag+ (aq) + SCN (aq) -------> AgCl (s) --------> AgSCN (aq) In one analysis, 25.00 mL of 0.01840 M AgNO3 (aq) was added to 50.00 mL of a solution containing dissolved chloride. The resulting AgCl (s) was filtered and removed. The excess Ag+ (aq) remaining required 14.25 mL of 0.02008 M SCN (aq) to reach the endpoint. What is the original concentration of Cl (aq) in the original 50.00 mL soln?

An acid-base indicator, HIn, dissociates according to the following reaction in an aqueous solution. K. Hin HIn(aq) = In (ag)+ H* (aq) The protonated form of the indicator, HIn, has a molar absorptivity of 2777 M-1.cm-1 and the deprotonated form, In¬, has a molar absorptivity of 19024 M-1·cm-1 at 440 nm. The pH of a solution containing a mixture of HIn and In- is adjusted to 5.86. The total concentration of HIn and In- is 0.000184 M. The absorbance of this solution was measured at 440 nm in a 1.00 cm cuvette and was determined to be 0.884. Calculate pka for HIn.
