Until now, I have only heard about the hydrogen electrode, and now I see it in practice for the first time. Thank you for this brilliant video 😊👏🥇
Awesome
very clear. Love this.
Thanks man ❤
Why not have the intermediate as 2NO at 11:47 does that work for an answer?
bro why did we connect SHE always to -ve and the other to positive?@KEGS Chemistry
Thanks so much sir
Can you please suggest where can I get these apparatus ?
From Egypt Thanks❤
This was vary useful thanks for sharing
What are your probes made of? I tried this with copper wire and it seemed to cause a chemical reaction!
looks like carbon/graphite
Does anybody know when I can buy the glassware to make a SHE? I am a lab technician in a school.
رائع وواضح كأن يحتاج ترجمة حتى يسهل على الطلاب فهمه.
Thank you. I learnt something especially changing the maximum from being to but choosing the minimum to be -20 and flipping the axis. Thank you. I subscribed.
what is there in conical flask in 2nd case
Good explanation
What order of reaction is this sir?
It's zeroth order as the concentration of iodine doesn't affect the rate of the reaction
thank you for this helpful video
Wow, this makes perfect sense. Thank you for finally answering this (apparently) obscure question!
❤thanks dude for this
This is so interesting 😮
THANK YOU SO MUCH FOR HELPING ME THIS FOR AP CHEM OML
Thanks a milliion
thankyou so much this was very helpful xx
Thank you so much sir for this video. I've been struggling with mole ratios and this video helped me.
lovely bro
lovely ♥️
Great video!!
Thanks. Tic marks on the secondary axis?

Is the ink water soluble?
Hey, is there anyway you could privide sources?
nice im going to prepare some now!
This doesn’t make any sense how do you just guess it
A truly gorgeous video of the utmost quality
Nice one Pankil, ur commet got 2 likes already
Thanks a lot!
What is the voltage requirement to kick in electrolysis?
The lower the v the slower it works but it doesn't matter much
Legend lad
I have a question. Please why is hydrogen gas needed to flow into the set up?
Because his potential diff 0
how exactly do you identify whether a step is slow or fast
not sure if you still need to know, but it will tell you in the question
dude i love how ur so happy with the graph. Great video !
Amazing
Bro! You Are Awesome Nothing is Better Than Practical Knowledge👍🤩 I am Truly Grateful To You

But the starch is an indicator, you were supposed to add it to the iodine before titrating
As he points out at minute 1:14, the starch is added close to the end-point to avoid inaccurate results because of strong bindings to the iodine
How to indicate the endpoint when the potassium iodide is in the burette during titration?
It's never done this way as you want excess iodide in order to generate a quantity of iodine that is directly proportional to the number of moles of your analyte. If you look at this video it explains more: kzread.info/dash/bejne/Zo2Nz8yYf9e1hpc.html
Great tutorial! Thank you 🙏🏻
Is it possible to perform this experiment by filling burette with iodine and conical flask with sodium thiosulfate?
I've never seen it done this way! It would make the colour change very hard to detect as iodine would bind to starch present and make it go black immediately after addition. It would then fade and come back when you added more. Thiosulfate in the burette is much better!
