Question: Why do solutions have different colors?
The purpose of this experiment in the lab is to measure the absorbance of five different solutions. These solutions were CoCl2, NiCl2, FeCl3, CuCl2, and NaCl. The color of the light that is transmitted by a solution or reflected by a particular object is the perception of the object's color. When light is transmitted through a solution, some of the photons are absorbed while the others are transmitted through it. The photons that are transmitted through the solution creates the light that we can see.
