![1. The dissociation constant for HIn (a weak acid) is 1 x105. At 500 nm, In has a molar
absorptivity of 628. HIn, however, does not absorb at this wavelength. A solution of HIn was
prepared by adding 1.00 mole of HIn to enough buffer to yield 1 liter of solution. The
absorbance of the solution was 0.252 at 500 nm in a 1.00 cm cell. Assuming that buffer does not
absorb at 500 nm, calculate the pH of the indicator solution.
Please Fill out this Table.
