What if I drain the burrete completely and fill again? With a burrete that measures 0(at top) to 100ml(final marking) above the valve, is the measurement stopped at 100ml? Or is the burrete completely drained and that equals 100ml down to the last drop?
The measurement is stopped at the 100ml line. So in order to have correct data, you would have to stop the titration process at the 100ml mark and refill it at that mark. Otherwise you would have added a certain volume of fluid to the beaker or whatever you use below the burette.
it's a science thing. We should always have uncertainties at the end of our measurements to account for the limitations of the instrument and the experimenter.
i love this very helpful! It's so nice to see chemistry being taught by a woman with such a beautiful accent!
I've always struggled with taking volume measurements off of glassware, but this video was super helpful! Thank you!
Thank you for this video, it helped out a lot when doing my virtual titration lab!!
😊This is where l did my Chem lab experiments this year 😊😊😊 My school 🤗
Congratulations
great explanation, very helpful, thank you!
Very professional presentation, thhank you. M.G.Sawicki PhD
This is making me smarter
This made my day
honestly
Why are the numbers upside down?
Great explanation, thank you 🙏
Wow, thanks for all the details
Thank you wits university
Very helpful
Thank you so much the video helped a lot ❤️
Well explained
Thank you
^^

amazing explanation thank you
Where is the meniscus
Thank you very much for this fantastic work, you are really so cute and I love you so much 💙💙💙
But why above is 0,01 and 0,03 middle is 0,04 and 0,06 and below is 0,07 and 0,09
Thanks that's awesome 👌
Wait 12 seconds then pause XD.
masheh boss
Why do we estimate the last digit of the volume?.
it's a science thing. We should always have uncertainties at the end of our measurements to account for the limitations of the instrument and the experimenter.
in fact you can only report until the first decimal
our teacher suggested this v cool 😻😻
Omg!!!!
uwawz 🤩‼️
any student from UP😅
omggggggggg
Very helpful
