Answer:
If we increase the concentration of a solute in a solution, it can lead to a greater number of solute particles in the solution. As a result, there is a higher possibility of interactions between the solute particles and light. This can cause the solution to appear darker or more intense in color.
So, if we decrease the concentration of the solute in a solution, there will be fewer solute particles available to interact with light. As a result, the solution may appear lighter or less intense in color.
