Look at the potassium permanganate. notice that very litle purple light is transmited through the solution. explain how this solution can be purple. it can be purple because the greenish/yellow light being shone on the solution is absorbed, reflecting the purple light. a student makes the statement "a solution is yellow because all other colors except for yellow are absorbed." evaluate this statement. could it be true in some cases? if it is not always true, how else could it be yellow? write a beter statement to explain why solutions appear a certain color. this is not always true- all other colors besides yellow are not necessarily absorbed. the reflected or transmitted colors which all reach the eye, mixed or blended together have a characteristic appearance. it could be yellow if the colors reflected mix together to appear yellow. a solution appears yellow because of theway our eyes sense the various frequencies of light reflected.
