Which one is the focus ofthis experiment?O the molar absorptivity coefficientO concentration of the absorbing substanceO thickness of the sample containing the absorbing substanceQ3. In experimental Procedure, Part A.1.: For preparing a set of standard solutions ofFeNCS, the equilibrium molar concentration of FeNCS2* is assumed to equal theinitial molar concentration of the SCN in the reaction mixture. Why is this assumptionvalid?O The high concentration of the SCNion ensures that the reaction is favored to the rightO The low concentration of the iron ion ensures that the reaction is favored to go to the rightO This reaction will not reach equilibriumO The high concentration of the iron ion ensures that the reaction is favored to go to the right

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. eb of In [HIn] pH
