Super sir

[@yuvashreer8453]

Excellent sir

[@heyits_harshu]

Thnku sir

[@faizasandhu_]

I watched some parts of the series. It is quite good, but you didn't mention anything about junction potential which is really important in potentiometry. Actually, this is what I was searching for...

[@user-uf6qx1zk5b]

thanks sir

[@poojasharma-xh5xk]

Thanks a lot sir

[@amrish1316]

Thank u sooo much sir ....u are the best😻 i finally understood the concept which was diffuclt to me

[@mukeshbbs5990]

Thank you soo much ..Its was excellent and very useful

[@RajendraSingh-hs1xj]

Reference electrodes is filled by saturated KCL is ok, but glass electrodes filled by saturated KCL.....?

[@pharmasolutionpakistan7668]

good

[@Shwetabatra24]

Hello sir...all of ur videos r of great help n i always choose to watch ur video in case of any issue...but my concpt regarding glass membrane electrode n calomel electrode is not cleared...i felt the video was short...
Also please mak video on voltammetry if possbl...

[@pkclasses100]

Please watch again the complete playlist of potentiometry from part 1 carefully, hoping your doubts will be cleared.

[@Shwetabatra24]

Sir iv watchd all the videos...like u told the three obsrvations of glass memberane electrode but u didnt told how it is happng wat role does kcl ag agcl is playing wats the mechanism...thats y i foud the the video ended bit earlier

[@pkclasses100]

Now it's not possible for me to edit or extend that video so I will advise to follow the book for more details as per your need.

[@Shwetabatra24]

Ok sir..
But again a huge thanks for ur work...! I always try to undrstand from ur video first in order to mak a rough picture of the process n c buk later...

[@yojanakurhade6453]

ion selective electrode me kya likhna he plzzz batao

[@lozinajaved979]

Here is a very good explanation but my concept is not clear about role of reference electrode and when reference electrode act as anode or cathode in glass membrane electrode and how it will behave when pH change? kindly give me ans of my questions?

[@pkclasses100]

Lozina Javed
Please go through potentiometry playlist and watch 4th 5th and 6th video. I would like to suggest you watch all 9 videos to clear any confusion. If still anything not clear then let me know.
Thanks

[@lozinajaved979]

ok sir thank u so much

[@lozinajaved979]

I have watched your videos my lot of questions are now cleared and thank u so much for it but still my brain is stuck in one point that how will reference electrode act, means when pH of sample is acidic how will reference act, either anode or cathode ?

[@pkclasses100]

Just Assume..
Reference electrode acts as Anode and Indicator electrode acts as cathode.
Both the electrodes are separated by a chamber and filled with KCl solution or buffered KCl solution.
So, potential difference between two electrodes will be ideally zero or you may say pH will be 7.
Now if we will put the electrode in the solution then inside the indicator electrode H+ ion will either increase or decrease. So their will be difference in the potential with respect to reference because reference electrode still having only KCl.
If H+ ion will be higher in sample/solution then it will go inside the indicator electrode chamber and pH will increase.
But if H+ ion conc. is low/or any base is present outside like OH; as compared to indicator electrode (which is buffered, but H+ ion present) then H+ ion will come out from indicator electrode due to concentration gradient and pH will increase in the indicator electrode.

[@shyamagrawal8426]

what is purpose of porus membrane between solution and reference electrode section?

[@poojasharma-xh5xk]

Sir.... Please... Gas sensing probe topic ki video dal do

[@kollibalakrishna314]

Nice explanation sir, but how can be 0.1m HCl in the bottom alone as it is already filled with KCl solution

[@ommahajan45]

Same doubt...?

[@Miracles.And.Effort]

4:38

[@KO-pu4pu]

Explain clearly

[@na-chan163]

how would the pH be known? Isn't that connected to a voltmeter? so only the potential is read. I'm confused.

[@artisharma9318]

Sir ion exchange electrode ki construction and working bhi kara de ..

[@nanotechnology107]

Sir Ag/AgCl electrode acts as indicator as well as reference electrode?

[@ganeshc8732]

Ion selective sir

[@hiteshvishwakarma6449]

Upload videos on X ray diffraction

[@alttechhindi3560]

Why only kcl is filled as electrolyte

[@mandosahu6972]

Ion selective electrode ka constitution bhi btaiye sir

[@RARasoi]

Sir ph meter pr bhi vidio bnaiye

[@sutharsavan1705]

Sir ye glass electrod ph meter ko kese massage pahochata he

[@niveshgupta2863]

👌👌👍👍

Pls prefer hindi

[@pkclasses100]

Yes.... Already started
