Homework Statement
A solution of Co+2 ions appears red when viewed under white light. Which of the following statements is true?
A) a spectrophotometer set to the wavelength of red light would read a high absorbance
b) if the solution is diluted, the amount of light reflected by the solution will decrease
c) all light with a frequency that is lower than that of red light will be absorbed by it
d) electronic transmissions within the solution match the wavelength of red light.
D is the answer.

The Attempt at a Solution
[/B]
I originally put down B as if I have a diluted solution, then my light absorptivity will change by beer's law. However, the text says that the amount of light reflected is the same, regardless of concentration.
I do not understand why the text says so and why D is the right answer (and why the other ones are wrong). Could you please help?
Thanks in advance!
