Chapter 10, Problem 10-73(choose chapter or problem)
Spectrophotometric properties of a particular indicator are given below: max 395 nm max 604 nm 395 1.80 104 M1 cm1 604 4.97 104 M1 cm1 604 0 A solution with a volume of 20.0 mL containing 1.40 105 M indicator plus 0.050 0 M benzene-1,2,3-tricarboxylic acid was treated with 20.0 mL of aqueous KOH. The resulting solution had an absorbance at 604 nm of 0.118 in a 1.00-cm cell. Calculate the molarity of the KOH solution.
