    Let's Suppose you are worried that you've developed diabetes, a condition in which blood glucose levels rise and glucose accumulates in the urine. Recalling what you learned in class, what could you do to determine you have diabetes? 
    • A. 

      Collect some urine, find some Sudan IV and perform a Sudan IV. As in class, a reddish-orange precipitate would indicate the presence of high urine glucose

    • B. 

      Collect some urine, find some Biuret Reagent Test and perform a Biuret Reagent Test. As in class, a reddish-orange precipitate would indicate the presence of high urine glucose

    • C. 

      Collect some urine, find some iodine solution Test and perform a iodine solution Test. As in class, a reddish-orange precipitate would indicate the presence of high urine glucose

    • D. 

      Collect some urine, find some benedict's solution and perform a benedict's test. As in class, a reddish-orange precipitate would indicate the presence of high urine glucose

  • 10. 
    How do you verify that a soft-drink can contain diet soda rather than soda sweetened with fructose>
    • A. 

      Test the two liquids with a Sudan IV test. Soda sweetened with fructose will test positive (for a reddish-brown precipitate), while diet soda will give a negative test and the benedict's solution will remain blue in color

    • B. 

      Test the two liquids with a benedict's test. Soda sweetened with fructose will test positive (for a reddish-brown precipitate), while diet soda will give a negative test and the benedict's solution will remain blue in color

    • C. 

      Test the two liquids with a Lugol's test. Soda sweetened with fructose will test positive (for a reddish-brown precipitate), while diet soda will give a negative test and the benedict's solution will remain blue in color

    • D. 

      Test the two liquids with a Biuret regent's test. Soda sweetened with fructose will test positive (for a reddish-brown precipitate), while diet soda will give a negative test and the benedict's solution will remain blue in color
