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!!
Why are the numbers upside down?
great explanation, very helpful, thank you!
😊This is where l did my Chem lab experiments this year 😊😊😊 My school 🤗
Congratulations
This made my day
honestly
This is making me smarter
Wow, thanks for all the details
Great explanation, thank you 🙏
Thank you so much the video helped a lot ❤️
Where is the meniscus
Very helpful
Thank you wits university
But why above is 0,01 and 0,03 middle is 0,04 and 0,06 and below is 0,07 and 0,09

Very professional presentation, thhank you. M.G.Sawicki PhD
Well explained
amazing explanation thank you
Thanks that's awesome 👌
Thank you very much for this fantastic work, you are really so cute and I love you so much 💙💙💙
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 😻😻
Wait 12 seconds then pause XD.
uwawz 🤩‼️
Omg!!!!
masheh boss
omggggggggg
any student from UP😅
Very helpful
