    This was so confusing to me when my teacher made us do it during class but after your video I realize it was actually so simple.
    Thank you so much, you truly helped me!!

    can i use the equation in serial as well? as i find that easier

    Hey!! The volume of the serial dilution ten fold changed from 10 cm cubed to 9 cm cubed in each test tube, correct?

    how do you get like 10 cm^3 of each successive solution when doing a serial dilution. like when diluting by a factor of 10 and have each successive beaker with a volume of 10cm^ as what stays in it

    Does the quantity of the initial solution decrease by sharing the solution in order for other ones to form?

    thank you so much! In case the original stock solution was 40 cm^3 (for serial) with 10% concentration, how much of it would we use to make it to 1%? And what would be the volume of water used?

    • @Lking123
      @Lking123 2 ปีที่แล้ว +2

      Starting with 40 cm^3 (for serial) with 10% concentration, if doing serial dilution you would simply remove 1cm3 from the original stock solution, adding it with the second. Then adding 39 cm^3 of water (diluent) to the solution. Allowing you to have a 1% concentration, so in this case it only took one dilution.

    In serial dilution , is it crucial to the experiment that the volume of water is greater than volume of the starting solution?

    Hi, can we take 5 cm^3 soln and 5cm^3 water for serial dilution or does the soln needs to be less than water? I really hope you notice this

    Hello, I have a question: Do you know how to find the no. of dilution, if both initial and final concentration and the volumes (initial and final) were given? I hope you notice this and answer. Thank you so much!

    • @JoPhillipsBiology
      @JoPhillipsBiology  2 ปีที่แล้ว +2

      Hi. I’m not sure what you mean by the number of dilution? If you mean how many times has the initial solution been diluted to get to the final solution, it would depend what type of dilution you were doing and what dilution factor was being used.
