This short video is embedded in a module for a chemistry course. Alone, it may not be that useful. Learning is a journey - enjoy.

No conclusion!? Too bad.
It was meant to be used with teaching to allow the instructor to decide how to incorporate it into their lessons. Thank you for viewing it. Did it bring any questions to mind?
Thank you! I just covered this in a lecture and was so confused and now it makes a whole bunch of sense.
It is a great honor and pleasure for me! Thank you very much!!
Love this video from India 😌🫶🏻❤️🩹
Hello classmate... Chemistry pa
😍
Thank you so much mam!!
anyone got the answers for the lil lab sheet thing
Aguyy
I like this version (#1) better than the other two (#2 & #3). This version does a great job of also showing the solvation of the ions by the water molecules. Only question is why not have the Ag atoms silver in color? This is an excellent animation to show the process. Thank you
Thanks a lot. Very helpful
This is as interesting as watching paint dry
LOL! Yes, I agree. This was not made for entertainment. Sorry.
hi can you explain the redox reaction in terms of oxygen
In terms of oxygen - why are or were you interested in oxygen? Can you tell me more?
@@resakelly2625 I just wanted to know....
The difference in oxidation states is mostly by 2. But in transition elements it's by 1. Why is it so? I'm confused in the transition elements
I think it is great that you are curious about this. It might be that the d sublevel is always one energy level behind the s block (ex. 3d is preceded by 4s), and since electrons are lost from the outermost energy level first, the atom would lose electrons from the s sublevel first. The s sublevel usually contains 2 electrons.

Porque?
Awesome 👌
Thanks 🤗
To get the lead out😂 ngl, that was hilarious!! I love you and your content ❤️ Helped me a lot✨🙏
Ohhhhoho 😗
So much thanks ❤️
Hi i just I want to ask if you have a summary word of your work?
I do not have a summary word. Do you have a suggestion? Hopefully not boring or painful.
Hey hii
Hii, what is the purpose of electrical conductivity in a redox reaction?
Electrical conduction tests for the presence of aqueous mobile ions in solution.
If a match is placed close to any chemical it will burn all over. Those matches should be ignited without dipping in any chemicals. When the match is about 1 inch or 5 inches away from the chemical radiation, it should ignite throughout. Tell me a little about whether it is possible with chemicals
Thanks!! its really helpful

What is your observation/result of the experiment?
In the second beaker silver nitrate, you add that silver accumulates on copper wire.
What is that thing that formed around the copper wire?
E😂
This is a pure redox reaction
Naliligaw ka ata kapatiddddd
Love your videos!💯❤️
Loved your enthusiasm and fun while explaining this Studying becomes so much more interesting when someone explains us with such great enthusiasm Your tone had a really good vibe Thanks a Lottt💯💯❤️
How is 2 a bent structure? I am not understanding that. Isn’t that compound tetrahedral
It is a tetrahedral if Carbon is the center, but if you consider oxygen as a center, it has two unshared electron pairs and two bonds, thus it is bent.

Very nice video, bro
What is the type called when the wire started to look like wool when put into silver nitrate?
KEIKO XD

Thank you
Creo que va a ser una actividad de la Pucp, así que lo traduciré: Experimento de reacción Redox Agua destilada Test de conductividad eléctrica Nitrato de plata Nitrato de cobre (II) Test de conductividad eléctrica (por segunda vez) Alambre de cobre Test de conductividad eléctrica (por tercera vez) Alambre de cobre después de que la acumulación fue removida.

Very good
Hello prof, Hope you are fine. Thank you for sharing your videos. How can I design like these animations. Knowing I have TD in Seince secondary education from American university of Beirut.
Learn how to use Maya software and/or take an animation/illustration course. I hired animation artists to help me.
@@resakelly2625 Highly appreciated
Hi! I'm wondering, what's the concentration of the silver nitrate in the second beaker? Would the concentration have a noticeable effect on the reaction, or does it not matter?
I did not calculate the concentration when I did this experiment - so the solution is of unknown concentration. If the concentration were known, I might be able calculate the amount of copper it would take to react completely or I could predict the amount of solid that is formed. if I also knew the amount of copper used. Additionally, a more concentrated solution, might have an effect on the reaction rate, but we would need to study this to find out.
Could you write me the Formula for what is happening here? I get that the silver nitrate is reduced and that the copper is oxidised, but how would you write this Ionic equation in its entirety?
I could write the equation, but I wish not to. I hope this does not upset you. The purpose of the videos I make is to serve as a tool for instructors to have students discuss what they view. I would rather not prevent them from being able to have a meaningful conversation about it. However, If you can find a General Chemistry textbook, search for redox reactions, you should find a solution. OpenStax.org has textbooks available for free.
(Cu2+ + 2No3- ) ---> (Cu + 2No3 - + 2e -). E(V) = -0.34V (2AgNo+ + 2No3- + 2e- ) ---> (2Ag + 2No3-) E(V)= 0.80 ∆E(V)= 0.46v ----> Reaction proceeds as written. You get 0.46V per mole ratio; set multiple reactions in series and you can get higher DC voltage. Since we know that E(v)cell is positive the free gibs formula ∆G=-n*F*E(v) predicts that the reaction is spontaneous; which it is as evident in the video. So you get 2 moles of solid silver for each mole of copper anion in solution.
got a link to the music?
Sorry, I do not.

Thank you for making these videos,it made me find Chemistry and Physics are related and interesting!
Glad you like them!

Please do add this to yt shorts so that everyone can understand just change aspect ratio 1.1 Nice video
what is that white stuff on the second beaker?
I'm not sure what you are referring to?
She means the white algae-like thingy that accumulated in the copper wire
I guess it is silver, since copper displaces silver from its salt solution
