The reason for the 30% more absorption for a solution containing 50% ethanol than the solution containing no ethanol needs to be explained, if both the solution contains the same amount of nickel. Concept introduction: Spectral lines are lines which help identify atoms and molecules. These are a result of absorption or emission of light in a comparatively narrower frequency range compared to the frequencies nearby. In a defined space, the amount of a substance gives its concentration. The capacity of a substance to absorb a specific wavelength of light gives its absorbance.

Question
