(c)
Interpretation:
It is to be determined in which manner the wavelength of maximum absorption would shift upon replacing a
Concept introduction:
The oxidation state of an element is defined as the number assigned to the element which represents the number of elements lost or gained by the atom in the given compound. The oxidation state is directly proportional to the crystal field stabilization energy and crystal field stabilization energy is inversely proportional to the wavelength.

- Potassium hydrogen phthalate (KHP) concentrations can be determined through titrating samples of KHP (a monoprotic acid) with bases such as NaOH in the presence of an indicator such as phenolphthalein. The indicator is colorless in an acidic solution and turns pink in an alkaline solution. Thus, we can establish an equilibrium for the phenolphthalein with the following reaction. HIn + H2O ⇌ In− + H3O+ If the HIn species is "acid color" or colorless for the phenolphthalein, and the In− species is "base color" or pink for this particular indicator, what color will appear in a flask in which a 0.2993 gram sample of KHP is completely neutralized with an excess of NaOH?
