Absorbance is a measure of the proportion of monochromatic (single-color) light that is absorbed as the light passes through a solution. An absorption spectrum is a graph of absorbance as a function of wavelength. High absorbances correspond to large proportions of the light entering a solution being absorbed. Low absorbances signify that large proportions of the light are transmitted. The absorption spectrum of [Ti(H₂O)₆]³⁺(aq) is shown in Figure 24-26(a).

(a) Describe the color of light that [Ti(H₂O)₆]³⁺(aq) absorbs most strongly, and the color of the solution. 

(b) Describe the electron transition responsible for the absorption peak, and determine the energy associated with this absorption.
