pH Meter | working of glass electrode of pH meter 

In my uni career studying chemical engineering i have watched hundreds of these type of explanation videos. This, by far, is the best one i have ever seen. Your explanation is impeccable. Subbed

This is the best video I've seen on the principle of pH meters. You simplified it in a good way. subscribed

Exam ke 1ghante pehle dekhi yeh video Bro is life saver ❤😂

Very well made! The concept, the illuatrations, great work!

Best video so far in explaining how electrodes work!

Explained very well and got some clarity about this topic

The Best Simplified Explanation so far on youtube...thanks alot 🙏👍👍❤❤

Brilliant explanation! This video has explained in detail how potential voltage is produced when there is a difference in the number of H+ ions accumulated outside and inside the glass bulb. Thank you

This is the best explanation on pH meter. Thank you very much 👍

The best lecture on pH meter ever. Thank you so much.

This is best video to understand the ph metry topic. Thank you so much. Excellent explanation.

Thanks from the core of my heart ... For such a Nice presentation And making concept Crystal clear.....

This is the best explaination of ph meter that ive seen here on yt by far ! U explained it even better then my teacher;) thanks

The best video about PHmetro. Thank u.

This is the best video I've seen for explaining the pH meter..Thank you sir for the lesson.🫡

one of the best vedio...full concept

I neeeeded this. I am a biotechnologist. It cost me some time to understand. Thank you so much for this video.

Explained Very well... Thank You 💚

Wonderful it cleared all my concept

Very well explained It’s complicated theory however you have simplified

ohh nice . well done

VERY GOOD AND DETAILED EXPLANATION, but I have still a problem (at time5: 31) Why is it that if the electrode is enriched with - charges (because it's an acid, and therefore has a low pH), the measured potential is nevertheless greater (and positive) on the graphs? Is this due to a departure of - charges towards the op-amp input, leaving a positive potential equal to that of the glass electrode? In any case, in the explanation given, between the positioning of the electrons on the central electrode (in the case of an acid), which would suggest that locally the potential at the end of the metal electrode is negative, and the fact that the potential measured at the op-amp input is positive, it seems to me that a step is missing in the description of what happens in the glass electrode. Of course, this is symmetrical in the basic case. How do you go from an electron-enriched electrode (acid case) to an electrode providing a positive input potential to the op amp?

This is the best explanation 🎉

Great work.. Video is well made... concept is clear.. Thankyou sir for this great video.. ❤️✨

Brilliant! Thank you so much for this video!!!

Excellent explanation

Thank for your excellent lecture 🙂

Thank you sir for the best explanation

thank you very much sir ! well explained

Very nicely explained

Very well explained

Thanks for the video.. you saved me😭😭

This is the best video on this concept that I have found. Thank you so much for the clear explanation

Well explained

Excellent video. Thank you for making this. It's really useful for me!

good graphics and explains

This vidio is well explained

When you say that the H+ from the external solution (to test) makes the inner H+ accumulate to compensate the charge difference, it seems incorrect as what will happen in this case is an accumulation of Cl- because the electric field produced by the H+ ions will repel the inner H+ and attract the Cl-. Can you please explain why then will the inner H+ accumulate on the surface of the glass ?

I have a question, Some documents say that the glass electrode side is filled with "pH7 KCl buffer solution" which is different from your information which is "HCl 0.1M" at 1:07 time . Can you help me explain this problem? Thank you very much

Best ❤

Sir what about the OH-ions?

A question. At 4'30", why the number of H+ ions in the inner and outer layers of the glass have to be balanced?

I do not understand why the inner H+ ions move to the internal glass surface when the outer solution is acid. Should't they be repelled since they have the same positive charge?

❤❤

Real good sh*t

How H positive enters into electrode

my question is ........... what is the function of saturated KCL .............??

Something may be wrong, H+ and H+ repell each other. F e. 4:30

Why the accent

Till before watching this video i had not understood the concept literally mugged up after watched this seriously very catchily registered in my mind 🤍🤍🤍

Well explained
