We did a LAB where we used a spectrophotometer to measure the absornency of a solution. It was a bluish color, so the question is....

What could be done to modify this experiment if the original solution was colorless? HINT: you can NOT add a coloring agent such as food coloring because then you will be measuring the concentration of the coloring agent , not the colorless solution. Think butterflys and night vision goggles.

i have no idea

thanks.

    Your hint suggests looking at IR and UV absorbtion.

    Thanks so much!!
