Suppose a future student receives an copper sulfate solution unknown that is so darkly blue that no light can be transmitted through the sample and she can't determine the concentration. What should she do? A) Discard the copper sulfate solution in the chemical waste container. B) Dilute the copper sulfate solution with a carefully measured volume of water and try the measurement again. C) Add a few millilters of water directly to the cuvette to get a solution with lighter color. D) Ask her lab partner what their results were and just use the partner's data.
