Answer:
The question is not complete, below is the completed question:
Increasing the cuvette width ___________ the absorbance because the light has to travel through ______ of the light-absorbing solute.
choices:
decreased, less
decreased, more
increased, less
increased, more
The correct answer is:
increased, more
Explanation:
Absorbance or optical density refers to the amount of light absorbed by a solution, and Beer-Lambert's law relates the attenuation of light to the properties of the material through which the light is traveling.
Beer-Lambert's Law states that when light is incident through a medium, the absorbance is directly proportional to the concentration of the solution and the length of the light path (cuvette width). This means that the more the concentration of the solution and the longer the width of the cuvette through which the light passes, the more the absorbance, because the light travels through more of the light-absorbing solute.
