Your videos are clear enough for anyone to understand.
Thank you for your efforts.

[@hikmatullahahmadi3542]

Sir I saw your all videos you’re the must great teacher I hope you make more videos thanks

[@AsifResearchLab]

Thanks dear

[@tuhocr]

This is so helpful video that makes the concept about pHpzc easier for learners. Anyway, in the last slide, you had a small typo: when the pH of solution is greater than pHpzc, the material surface will be negative charge. (you repeated the first line to the third line)

[@AsifResearchLab]

Yeah. Really sorry fot this unintentional mistake. And your comments will be help the viewers in understanding the surface change. Thanks for your valuable comment.

[@bushraazhar8018]

Informative video
Well done and keep it up

[@AsifResearchLab]

Thanks

[@khadidjakahoul7597]

Very helpful. Thank you

[@AsifResearchLab]

You're welcome!

[@fotensolution6504]

Thank you for your generous efforts to explain many complex theories for the scientific community. I think you have been doing great. Just to prompt you on something in relation to the above video. I think the determination of the change in pH should rather be like : change in pH=pHf-pHi. I noticed that you rather calculated it the other way round. @Asif Research Lab

[@AsifResearchLab]

Thanks for appreciating this work. Yeah you are there is mistake.

[@kuljitsihra17]

Well explained

[@maqsoodalispicher2494]

Very Informative Video..Keep it up

[@AsifResearchLab]

Thanks

[@hikmatullahahmadi3542]

You are the best

[@AsifResearchLab]

Thanks

[@meryemamar7161]

Thank you for your kind words. I'm excited to help explain complex theories to the scientific community. Regarding the video you mentioned, could you provide bibliographic references on the method discussed?

[@AsifResearchLab]

you can see my research articles

[@chemophile14]

01:00, what do you mean by equilibrium? How to know the system got equilibrium? Is there any color change?

[@AsifResearchLab]

Thanks dear

[@MohomedSalah-z4f]

Thank you a lot, its really helpful, do you have a video how to use read and set up new method the UV -Vis Spectrophotometer or hplc ?

[@AsifResearchLab]

Thanks and I will try to make video on said method.

[@saraswatdey5763]

" Desirable amount of the adsorbent should be mixed " but how much minimum amount of adsorbent should need to mix for 40ml solution?

[@anurana6349]

Thank you 😊

[@AsifResearchLab]

Welcome

[@sabaal-qaysi4171]

many thanks , regards

[@AsifResearchLab]

Welcome

[@salsabileben8028]

I will ask u when ph

[@poetry65]

I am only confused at one point. Can you plz elaborate? Actually In the last slide where u told about the three condition pH pHPZC.
Can you plz tell me which pH should I compare with PH PZC?
The initial pH or Final pH or difference of pH?
I'll be grateful.

[@dumisanigwebu2385]

Hi where can I get the formal methodology for this?
An article perhaps that I can cite for my research?

[@AsifResearchLab]

www.sciencedirect.com/science/article/abs/pii/S0141813020337405?via%3Dihub

[@AsifResearchLab]

read this article for PZC

[@hope2633cu]

What is role of NaNO3

[@nautamparasana9992]

bro can you help me out in determination of phosphorus in unknown sample using UV spectrometer ? means what should i do i dont know about it well

[@azkatariq5477]

Hi dear, you have been doing great job.
My question is what is the purpose of using NaNO3 solution? Can we use distilled water rather than NaNO3 solution for pzc determination?

[@AsifResearchLab]

No

[@osamahacham9580]

NaNo3 used to get a constant
ionic strength in pHpzc determinations.

[@valentinaparedes6375]

The concentration of nano3 state sthe same even if the amount of product used of the analyte is low(0,5g)?

[@sorodhonipotshangbam1716]

sir , I have a question regarding the calculation of Ph using the Henderson. Suppose I want to make phosphate buffer of Ph7 , I took monobasic and dibasic sodium hydrogen phosphate each of 0.1M. But I dnt get the desire Ph. Is there any rule for taking the concentration?

[@sourodiptomodak1994]

The Initial pH must be the pH of the Distilled water before starting the experiment, Sir? My distilled water pH is coming around 5.6. So can I use that water for finding point of Zero charge

[@AsifResearchLab]

You have to set a range of pH values for PZC determinination as illustrated in video.

[@geeteshkumar5919]

Sir, Thanks for the video. I have a question, can we use sodium chloride instead of sodium nitrate as because both are derived from strong acid and strong base. And we can adjust the pH using 0.1 M HCl and NaOH

[@AsifResearchLab]

Thanks. Main goal is to achieve required pH. Use whatever u want

[@sourodiptomodak1994]

The Initial pH must be the pH of the Distilled water before starting the experiment, Sir?

[@AsifResearchLab]

No. The value u set by adding acid or base.. range form 3 to 12 normally

[@ScotFish-g5h]

Wallace Court

[@geeteshkumar5919]

Sir, what is the amount of adsorbent to be added

[@AsifResearchLab]

Depends upon type of absorbent. Get help from literature according to ur absorbent.
