Well explained
Thank you.
One of the best videos Especially explaining bout ozonation and uv light treatment. Superb Thanks for your information
It's my pleasure. Thank you.
Is it same as ICP-OES?
Almost same except for the detector.
Thank you so much ma'am, very well explain in detail. One more help needed from you regarding fecal coliform test of wastewater.
It's my pleasure. I am not aware of that test.
It's my pleasure. I am not aware of that test. Sorry.
awesome explanation
Thank you so much.
Nice dear
Thanks.
AMAZING 🎉 Thank you so much mam
It's my pleasure.
Good. Teghhkcjhbcncmkhn vhjjhhjjjbvnchh jhjhjjjk
Thank you mam ☺️ 😊
Most welcome.
Mam can you tell me the reason of increasing potential when we add titrant
In the Nernst equation, the concentration of Fe3+ keeps increasing and the concentration of Fe2+ keeps decreasing till the equivalence point because Fe2+ gets oxidised to Fe3+ with the addition of the titrant. This is why the potential(EMF) increases.
@@RevathiPurushothaman thank you so much aapne kafi ache tarike se btaya ab mer doubt clear ho gye 😊
Need a Tamil explanation please..
I will try in future.
Thank you mam
It's my pleasure.
amazing teaching mam
Thank you so much.
your english sucks try to make videos in hindi language i think that will bw quite better. sorry for being rude
👍
thank you soooo much, the BEST explanation even better than my teacher, god bless you keep saving lost student.
Thank you so much. It's my pleasure.
nice explanation, but did not understand anything.
Watch it again.
Really, gr8,thank a lot Mam, This is the content I was searching for
Thank you so much.
My exm is in 1 hr
Thanks
Good explanation mam, Doing good job
Thank you so much.
❤ amazing lecture mam! ❤🎉
Thank you so much.
perfect
Thank you.
Thank you mam
Most welcome.
Your explanation is very good❤🎉
Thank you.
Maam, i think aftr screening we should not directly jump to sedimentation rather than we should do aeration, as aeration part is missing in this video, and maam thank you for your effort❤, very nice and knowledgeable video.
Thanks for your concern.
want electroless plating of copper
Ok
Thoda hindi me bhi samjao
Hindi me separate bana doongi future me.
Very nice presentation. Could you please tell me your source of information, book perhaps, in the videos in your playlist. Also, the link to your blog post. Thank you
I have refer many books and resources. I don't stick on to one. Thank you.
Very clear concept ,explanation madam Thankyou
It's my pleasure. Thanks
Best explanation of corrosion on RUclips!
Thank you so much.
Thanks a lot, beautiful explanation. Long live 😊
Thank you so much.
Mam please give link to the ppt of potentiomerric and conductometric titrations
Check my blog
Well understood. Thank you so much. 🤍
It's my pleasure.
Very informative, well explained ❤
Thank you so much.
I think you mean standard oxidation potential of Zinc at 6:12
Yes
Very useful information
Thank you.
Nice explanation ma'am
Thank you.
👍
Thanks
After demineralisation or ion exchange process TDS of water will get reduced? Pls reply thanks in advance 🙏
Yes. It will get reduced.
Damn i was trying to calculate this from normal titration curves. Seems like I need another experiment :(
how could we know whether the compound can be measured through fluorescence. and Can I use DPPH free radical assay for antioxidant with the spectrofluorimetry
Please Gujarati language 😅
Maybe if AI translations become good.
wonderful explanation MAM
Thank you so much.
Very well explained
Thank you
Excellent. Thank you so much.
It's my pleasure. Thank you.
Can i get the ppt file
Check my blog.
What if the colloidal particles are positive how will they be seperated
Nice explanation
Thank you.
Mam.. May I know the reference book for this content, please
I don't refer to one single source.
@@RevathiPurushothaman I'm a 3rd year pharmd student... So as a teacher what u would recommend me to refer
Thank you for this video. Clearly written and explained. Keep uploading more videos! Especially your written format made it very easy to grab the instrumental info of this content
Thank you so much for motivating me.
