Electrolytic vs Galvanic (Voltaic) Cell | Electrochemistry

This video gives you an in-depth comparison of the Galvanic/Voltaic electrochemical cell and the Electrolytic cell that operate on redox reactions to convert chemical energy into electrical energy and vice versa.
You’ll learn how to determine the oxidation and reduction half-reactions at both the anode and cathode, how to identify the charges on the electrodes in each cell, as well as the importance of the salt bridge in maintaining the neutrality of a half-cell solution.
You’ll also get a detailed review of the components of each type of electrochemical cell, as I show you exactly what’s happening with each species in the reaction, where the electrons are flowing and how the cell is being powered.

you have no idea how much you helped me in my first year as a pharmacy student. from Organic Chemistry to Basic Chemistry. God, you r truly a lifesaver

[manuelissiahrito]

i have an exam in 4 hours. Great explanation you just covered half of my exams concepts about electro chemistry in a 13min video!! Thankyou! Hope i passs..

[CarolynnCalin]

This is the best YouTube video!!! I’m studying for MCAT this summer and I couldn’t understand this until watching this video thank you!

[drewkovacs]

Thank you, needed this before big exam!

[ShepherdXVII]

First video that made this easy to understand!

[ellaberger]

This is an incredible explanation, thank you!! You clarified so many points for me! And the point about the battery being a voltaic cell driving the bigger electrolytic cell is SO interesting and makes a lot of sense!!

Hi ma'am,
Thank you for this amazing video, it really helped me understand the concepts instead of byhearting everything. Instant subscriber ❤️

[bjoie]

thank you for the video! but can you please tell me the purpose of this specific electrolytic process? what is it trying to do ultimately? what exactly does it start with and what exactly does it end with?
(NaCl, molten NaCl, Na+ Cl- all that stuff is just mixed in my head and I don't know where it starts and end!)

[generalrdthethird]

carried me for my chem exam, great video

[ruhulaminsiyamsyed.]

Thanks mam for the explanation, I was so confused becuz of this and tmrw is board exam on chemistry 😅

[rayrayyay]

you literally saved my life thank u so much 😭😭😭😭

[loe]

Amazing video and super helpful for studying for chem midterm, thank you!

[vishalmanickam]

Found the video when I really really need it

[errresh]

This video is amazing thank you so much.

[claudiabendezu-js]

I have a question.. so can you explain to me a bit more the part where you mention how the cl- goes to the positive electrode(anode) ….you said something about the electrons coming out of the battery which attracted the Na+ but then u lost me when u stardet mentioning the Cl- after that like how did the Cl- connect to it . Thank you I have an exam on Tuesday

[bunyamincileli]

I don't understand the part about the anode och cathode charges. I specifically don't understand why the anode is negative and why the cathode is positive.
Zink-ions leaves the zink plate and desolves into the solution, the ions are positive and leaving the zink-plate makes it negative maybe? And Zink has no charge so how can it be negative.
But what does this mean for the solution. Is it the solution that is negative and pushes away elekctrons from the Zink or is the Zink itself negative and pushes away electrons from itself?
And same for the cathode. Is it positive just because it picks up electrons?

[dolgoh]

super clear explanation!!!! thank you very

[yousifaburoos]

thanks alot for this simple yet effective explanation. have a nice day ma'am, please wish me luck I have an exam after 2 days...😅

[shynilogics]

Thankyou so so much
It meant a lot for me
❤❤❤

[aaaaaaaaaaaa-bj]

thanks a lot for the video but I have question; suppose zn loses 2 electron and becomes zn++
right
but it would have been easier to remember like zn loses 2 electrons and becomes zn-- (losing relates to negative)
