How a pH meter works!

You will learn how your pH electrode works. In order to have accurate results it is important to understand the tool you are working with. Digital pH meters with electrodes have a flow of electricity that no one knows about. Welcome to understanding pH

I have never seen such explanation of ph meter in youtube. Thank You so much. Love from india

[alvieteal]

Holy shit. I’m an electrical engineer and this is just way above my head. I came here expecting this thing to be simple.

[richardweber]

Thank you for your video! I’m a dentist and would love to pick your brain on the best way to quickly measure a persons oral ph throughout the day.

This lecture is really informative i wanna see this in literature, can you recommend a book?

[DnaKGames]

What a fantastic video. Great explanation.

[realitydamn]

From where the H+ ions are coming inside the kcl solution, as kcl solution doesn't produce h+ ions?

[이로운-mq]

thanks for your kindly explanantion. i am sure that it would be helpful for basic concepts of the ph meter if anyone take this lesson. to be honest, i am not good at listening english, but this video has a kind subtitle. it help me to understand your video. thanks for your effort again~~

How can the electrons flow opposite directions through the same wire at the same time?

You can make your own ph pen probe storage solution (3 molar KCL) with ph 4 buffer solution + potassium chloride.
Mix 1g potassium chloride (KCL) per 100ml ph buffer 4 solution to make 3 molar kcl storage solution. The gel dries out quickly if left in open air or is stored in reverse osmosis or tap water leeches potassium chloride ions as the probe tries to make equilibrium. Storing the probe submerged in 3 molar kcl storage solution is best for years of life out of the ph pen. Change the solution the probe is stored in every 2-3 months.

I really don't understand why lots of people in the US like to use wrong terms for certain things. There is no such thing as "8 mV of charge". Volts are units of (electrical) tension, not charge. Coulombs are units of charge.

I reckon this inconsistency and errors make a mess for people who are trying to get a grip of these things.

Also, this is a blackbox explanation of how pH meters work and it simply does not suffice even highschool levels.

Very informative. Thank you for making this video!

[christy]

long time I dipped the pH sensor into the solution means what will happen it's affect the sensor behaviour or not

[mohammadashrafqureshi]

so the ph value which i get is due the potential difference between the mesuring electrode and the reference electrode . another questiin is that what is the role of temp sensor in the ph meter .? and is it the aglc which transmit back the mv signal ?

[Xanthillium]

I'm confused, where is the kcl that leaked into the solution getting it's electrical potential?

[luisalbertlucio]

in minute 1:45 it says A high number of PH represents an acidic solution and a low number is a basic solution which is wrong, it is backwards right?

[hashamhexa]

Can u give chemical reaction or equations used in this reaction?

[pawanrathi]

Sir how can we determine pka of unknown solution using graph?
I'm confused with equivalent and half equivalent point. I'm not understanding which point we have to select for correct pKa value.
Can you please tell me with reference of any book or anything else.

Thanks 😊

i am confused we have filled 3 molar KCL hen from where hydrogen ion came inside .second some one says H ion get penetrate inside glass electrode through membrane and reaction takes place inside kcl get converted in to HCL and some one says it is due to gradiant formed between hydrogen ion

[omoredeaguebor]

Where does the H+ in the reference electrode come from

[vitorito]

Very good material. You should produce more videos like this one. Conductivity, os so.
