the fact that not every practical seminar starts with stuff like that should be a crime. ty
This is so informative thank you so much!!!!
Thank you
Just give me a 500W microwave oven!
a transcript would be helpful.
Do you have a transcript ?
I enjoyed this video, and it has helped me greatly in my Chemistry class for Introduction to Chemistry with Dr. Ngo.
Glad it was helpful!
very helpful!
Thank you. I'm glad you thought so.
Danke, sehr hilfreich!
I hope the volumes are also included sir but thank you ❤
no u cant daw 😢
Thanks for the video, sir! 😊 I hope I'm not causing any inconvenience, but would it be possible for you to kindly share the initial and final volumes for HCl and NaOH? It would be a tremendous help for my assignment. Your response to this would be greatly appreciated. Thank you so much! 🙏

これはとてもクールです!これもいつか試してみたいです! 😍
Atat nganong walay volume ang HCI og NaOH?

こんにちは!デモの各バッファー サンプルの最初と最終の HCL と NaOH の量を知りたいのですが、教えていただけますか? ありがとう!
wazzup guys
shout out sa mga classmate nako from emt na nastressed ani for labreport
helom rats HAHAHAHH
@@kyleabinestan shut up kyle 😒
Hello, can we know the volume of strong acid and strong base that were added to the buffer solutions? This will help us big time. Thank you
I have a Novaspec II device in my laboratory. but I don't know how to use it. When you plug the device into power and turn on the button, it says L fail on the screen. What should I do? Can you help me?
Thanks a bunch for this benefitial video, I learned a lot
Glad it was helpful! This is very reason I make these videos.
Is any difference in abs reading if we put aero side to left direction...??
No. As long as the cuvette was positioned the same way for the blank and solutions measurements, there should be no difference in absorbance readings.
Have my chem practical in two days, thanks!! :) Burettes always made me nervous in lab but hopefully I won't mess it up and get a bad grade
latino no entender ni mierda
Please Hindi meaning bhi use kr liya Karein apni matra bhasha h
Kya sir India ke hote hue bhi sb English me bol rhe ho
why should the burette not be completely emptied?
when dispensing from a burette
Thanks . The washing part is very important for me
You are welcome.
40 minutes before my practical exm . It's very helpful 👍
I'm glad it helped.
Arabic 👍🏻
Thanks for the video...really appreciate that 😄
You're welcome. I glad it was helpful.
Nikal
Thanks sir
You are welcome!
Hello, may I use your video for educational purpose in my class? I would like to add a voice over in my own language.
Yes, of course. Please do.
why do we still use the pipette? seems kinda outdated...
നാളത്തെ പരീക്ഷക്കുള്ള വീഡിയോ കാണാൻ അലഞ്ഞു തിരിഞ്ഞ് ഇവിടെ എത്തിയത് ഞാൻ മാത്രമോ 😁...
Shwiya
Very well presented. This is useful for improving the techniques of students of pharmaceutical analysis
Glad it was helpful!
Thanks a lot !
You are welcome!
Keep Going 😀
Thank you, I will
thank you so much...
You're most welcome
Nice video. One detail that I didn't see mentioned (maybe I missed it) is that when the delivery of liquid is finished, a small quantity of liquid will remain in tip. One should not attempt to shake or blow out this small amount of liquid. The pipette is calibrated to *deliver* the stated volume (not *contain* the stated volume), and it is calibrated with that drip remaining in the tip. A good experiment for students is to see, empirically, how much difference it makes by weighing what is delivered with and without that small additional volume being shaken out. Obviously, the *relative* error will be larger for pipettes of smaller indicated volume (e.g., 5-mL vs 50-mL).
Thank u
I watched this video first time and it seems so practical experience really so much nice...
yes the experience was very nice
I'm glad it was useful for you.
Can you guys comment the chemicals you used in this tutorial? It's hard to see the tiny letters.
Saturated Ca(OH)2 (for base mixture) 0.0105 M HCl (for titration) Phenolphthalein 1% (for color change)
Is there a need for pre warm up?
Thanks
It is very helpful for me because.. tomorrow is my practical
my viva😂😂
2 years late but still how was ur practical?
Same, today is mine
Is that the actual pronunciation? Because I always thought it was byo͝o-rĕt′
I have lab test tomorrow this helped a lot! Thanks
Good luck king
Gabe Newell haha aced it
Does this unit have any sort of graphical USB interface for PC? Is there any software available that provides a larger format, more detailed, full-spectrum absorbance graph on a connected PC..? 🤔 Or, is the onboard LCD screen it..?
