9.4.1 Explain how a redox reaction is used to produce electricity in a voltaic cell.

9.4.1 Explain how a redox reaction is used to produce electricity in a voltaic cell.
9.4.2 State that oxidation occurs at the negative electrode (anode) and reduction occurs at the positive electrode (cathode).

Hey man, you’re a good teacher. Great visuals and drawing everything out while explaining while you draw at the same time. Thank you. Had a very frustrating time watching other videos on this topic. 🙏🏾

[@abhilashmishra6356]

Thanku u teacher. Great understander

[@KochoshinobuofficiaI]

thank you very much sir

[@mra2534]

Thanks a lot🤩👏

[@aaravpant1082]

Well explained...

+Nithin Lal Thanks, just to let you know, there is a newer version of this video here: th-cam.com/video/l5-i5fgcHvU/w-d-xo.html

thank u sir

Thank u!

Good sire. Thank you for this 🙏
But what makes salt bridge an ion conductor but not electron conductor?
What is the electrolyte composition to be used? What are the guidelines if any?
Should the positive ion on the electrolyte be less reactive than zinc, but more reactive than copper?
Why do we need two electrodes? There is a redox at each node (at anode metal oxidized, electrolyte solution positive ion is reduced) so one anode is sufficient to produce electricity?

[@lupinsahu3863]

Ty sir

[@halabaitalmal2583]

ummm, wouldnt the anode be positive since its losing electrons and thus losing negativity making it positive?

[@MSJChem]

The anode of a voltaic cell is negative because it is the source of the electrons. By the way, this is one of my very early videos - my latest videos can be found at my website www.msjchem.com

[@nellvincervantes6233]

Maybe because more negative ions reside on anode while more positive ions reside on cathode, maybe thats why

[@mohammedarshak7801]

Why silver is 2 in the reaction 2AgNO3+Cu=Cu (NO3)2+2Ag and why it can't be written as AgNO3+Cu=CuNO3+Ag it is also balanced know?

[@MSJChem]

Mohammed Arshak Because copper is a 2+ ion and silver is a 1+ ion. The second equation that you wrote is not balanced correctly. The first equation is correctly balanced.

[@mohammedarshak7801]

Copper can be a 1+ ion since it is a transition element

[@MSJChem]

Correct, but in this case it is the copper(II) ion.

Good try

Well explained thanks but ok ok irritates alot
