Serial Dilution Quiz - Quiz

What do you know about serial dilution? Let's test it out now by this true-false based quiz. A serial dilution is basically known as the stepwise dilution of a substance in a solution. It is usually like the dilution factor at each step is constant, causing a geometric progression of the concentration in a logarithmic fashion. So, here are some questions to test you as well as to educate you more on the same. We hope you like this quiz.


Questions and Answers
  • 1. 
    If you've taken 250 ul of plasma and added 750 ul of distilled water, you have achieved 1:4 dilution.
    • A. 

      True

    • B. 

      False

  • 2. 
    You begin serial dilution. In tube 1, you add 100 ul of plasma to 900 ul of distilled water and get a 1:10 dilution.
    • A. 

      True

    • B. 

      False

  • 3. 
    Taking 20 ul from tube 1's 1:10 dilution and adding 80 ul of distilled water would achieve 2:100 dilution for tube 2.
    • A. 

      True

    • B. 

      False

  • 4. 
    Taking 100 ul from tube 1's 1:10 dilution and adding 900 ul of distilled water would achieve 1:100 dilution for tube 2.
    • A. 

      True

    • B. 

      False

  • 5. 
    If you've taken 500 ul of plasma and added 750 ul of distilled water, you have achieved 7:4 dilution.
    • A. 

      True

    • B. 

      False

  • 6. 
    You begin serial dilution. In tube 1, you add 50 ul of plasma to 450 ul of distilled water and get a 5:10 dilution.
    • A. 

      True

    • B. 

      False

  • 7. 
    1:100,000 would be the dilution in tube # 5, assuming tube 1 is a 1:10 dilution.
    • A. 

      True

    • B. 

      False

  • 8. 
    You've diluted 80 ul of plasma with 170 ul of distilled water for a 1:4 dilution. The test still reads as needing further dilution. You then take 200 ul of the 1:8 dilution and add 100 ul of distilled water.  You need to multiply your result by 17. Is it true or false?
    • A. 

      True

    • B. 

      False

  • 9. 
    If you've taken 250 ul of plasma and added 200 ul of distilled water, you have achieved 4:2 dilution.
    • A. 

      True

    • B. 

      False

  • 10. 
    You've diluted 100 ul of plasma with 300 ul of distilled water for a 1:4 dilution. The test still reads as needing further dilution. You then take 100 ul of the 1:4 dilution and add 100 ul of distilled water.  You need to multiply your result by 8.
    • A. 

      True

    • B. 

      False
