The chemical formula of the compound can be defined as the set of the chemical symbols and the elements which are present in the compound in their relative proportions.
(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.

- At 25 oC, Ammonia is a weak base that reacts with water according to this equation: NH3(aq) + H2O(aq) ⇌ NH4+(aq) + OH−(aq) Briefly explain how the equilibrium will shift (to get back to equilibrium) if the following perturbations are made to the system: (a) Addition of HCl (b) Addition of NaOH (c) Addition of NH4Clarrow_forwardPotassium 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? a.
