Investigators frequently use colorimetric tests to check for the presence of certain chemicals. For example, when the vitamin riboflavin is present with certain reagents it turns a solution bright yellow. When the vitamin pyridoxine is present with other reagents it turns pink. Suppose you are given three test tubes, one containing riboflavin, the other pyridoxine and a third containing an unknown (riboflavin, pryidoxine, or both). You are also given the necessary reagents.

(a) How would you check your unknown?

(b) What results would you expect if your unknown contained riboflavin, pryidoxine, or both?
