1. Would you say that indicator tests are qualitative or quantitative? Explain your answer. 2. a. How does the Benedict test detect monosaccharides? (be specific!) b. Why can't the Benedict's test easily detect the sugar units of a starch? How does the Iodine test detect starch? (be specific!) b. Why can't the sugar units of a monosaccharide solution be detected with Iodine? (hint: "because it's not designed to" is not the answer I'm looking for!) 3. а. 4. a. What was different about the two protein solutions? b. How does the Biuret indicator detect proteins (and thus only one of the protein solutions)?
