Greetings, I have a few inquiries about this video. As a college student, my thesis will involve investigating the presence of heavy metals in ground coffee. I want to know if ground coffee or other solid samples may be used with cyclic voltammetry. Thank you; perhaps you can respond to this query!
Please any one hlp me in solution this problem One gram of zinc metal dissolved in a solution of hydrochloric acid with a concentration of 6 molars, dilute it to 250 ml. Take 25 ml of it into a polarography cell, and the polarogram shows a voltage wave at -0.65 volts (assigned to Cd impurities), a diffusion current equal to 32 milliamps. If we add to the cell containing the zinc solution 5 ml of Cadmium chloride concentration is 0.0005 molar, and when taking a second crystalogram, the diffusion current was 77.5 milliamps. Calculate the weight percentage of cadmium impurities in zinc metal.
Nice video madam . I am searching more videos about CV . I was see so many videos but didn't understand videos . I saw your videos little bit understand . i need so many videos because i have zero knowledge about elactrochemistry. thanks madam
Congratulations on a very well presented demonstration, usually when I am exploring something new I need to search through everything on TH-cam and still left scratching me head, I got this in one. The only question I have is, what is the purpose for this experiment? My gut instinct is that it has similarities to mass spectrometry where the atomic makeup is identified with electrical resistance
Nice video, I think it is better to make a cap for the cell to set the three electrodes and to connect as follows: 1. Reference 2. Counter 3. Working ( the opposite on disconnection). Keep moving and do more videos, best wishes.
Wonderful video with proper protocols explained. Thank you for this awesome content. Looking forward for more videos on electrochemical techniques. I suggest you explain every performed techniques with protocols. Edit: Also, if possible, I hope you could upload a video explaining electrodeposition of species onto WE using CV, CA, CP techniques.
Thanku sooo much mam...we need more videos on CV please ...❤
Plz make videos for operating CV instrument how can we use it and how can we do parameters like Cv, DPv, LSV etc
Can you make a video to show how to use a three-electrode cell and how to add active material to the tip of the working electrode?
Magical button ( NOOOOOOOOOOOOO) your electrode positoon is not good ... thats why you dont have any type of result ...
first time your electrods are touch each other ... your "Black electrode" and Prob of "Red" is touch each other ...
Very impressive, explained very clearly, looking forward to learn more with you.
Wel explained. Thanks. It helped me better understand this technique.

Could you please suggest me a book so that i can grasp all electrochemical phenomenon that talked in this video lecture
bard electrochemistry book

You should remove you catalyst first by wibe it using tissue with water, as some times catalyst can scratch the surface
For the potentiostat you used, If i have a 2-electrode set-up, do I connect the red and white clip together?
Awesome video. Looking forward to more such content. Thank you for making this.
the electrolyte is of? like is kcl/ koh
How to solve the overflow problem? Plz help
what to do if error of digital to analogue circuitry showing upon hardware test ?
Very helpful ,,thank you
Thank you very. Excellent video
I love u baby
How we perform if we have powder samples??
thanks
Why do you store Pt in nitric acid bath? Since Pt is inert, couldn't we store out in a jar or something?
extra thump up for wearing protective gear including safty hoodie
Thank you very much....

impressive
Legend says She's still asking people to turn off the potentiostat
Great video, I like the way she explained, super cool

Need some more videos about this
Ma'am pls share pdf file of procedure CV
very nice explanation. Your camera person needs to improve though. Probably do a landscape mode?
Need more video 🤙🤙🤟🤟

very clear explanation. easy to understand.
Superb Looking forward more videos on electrocatalysis
