19.4 How to Calculate Standard Cell Potential | General Chemistry

Chad demonstrates how to calculate Standard Cell Potential (a.k.a. emf or voltage) from a Table of Reduction Potentials. He uses both of the commonly used equations and shows the difference between the two and where NOT to make a mistake.
Ecell = Ecathode - Eanode
Ecell = Ereduction + Eoxidation
The Standard Hydrogen Electrode (SHE) is also identified and its importance as a reference electrode is described. Finally, it is demonstrated how to use a Table of Reduction Potentials to identify the strongest oxidizing agent, the strongest reducing agent, and when two species will react spontaneously in a redox reaction.

Wow! This video was put together beautifully and I really appreciate you helping by making this topic simple for me to understand. This video has gotten me through the hardest times, every hurdle had in my life, I wouldn't be able to get through electrochemistry if it weren't for you Mr. Chad

[@ChadsPrep]

Glad the video helped you!

[@Roseshade667]

One of these days I'll start watching videos like this *before* the last two days before the final. Thanks for making this easier to understand.

[@ChadsPrep]

Very welcome.

[@dzzygaming]

possibly the best channel on youtube for this sort of information, explains everything needed to know, thank you a million times over man!!!!

[@ChadsPrep]

You're welcome, DzzyHD!

[@kartoffelkafer7986]

I could never find a better Chad! Thanks for making chemistry awesome!

[@ChadsPrep]

You're welcome and Thank You.

[@katierolicheck4183]

Thanks, Chad, your material has really helped me learn and understand my material in class better.

[@ChadsPrep]

You're welcome, Katie - Happy Studying!

[@Nomanismyname]

Chad!You really are a CHAD👑

[@ChadsPrep]

Happy Studying!

[@horsegirl9179]

Love this video and chanel... I'm so excited about the physics videos also being released, because I start that journey next semester.

[@ChadsPrep]

Love the enthusasim!

[@shabisepah2401]

Very Very Helpful. Thank you so much for such a good explanation. Now I completely understand REDOX reaction.

[@ChadsPrep]

You are welcome!

[@alessandrac1940]

thanks for simplifying this. when it comes down to it the math and the logic aren't that difficult, but i appreciate the clarity of your lecture (like all ur others)

[@ChadsPrep]

You're very welcome!

[@rachadaita7502]

Very Helpful! Thanks

[@ChadsPrep]

You're welcome!

[@thanvijain7379]

Can you please give the link of the video where you have explained di substituted, tri substituted alkenes ?

[@colossalepic7125]

Thank you, very helpful!

[@ChadsPrep]

You're welcome!

[@dom6783]

Hi Chad. Is there any way we can donate through patreon or something? You've helped me so much :)

[@max3eey]

His website

[@kagamer21]

Did you get a new camera? This video looks real sharp brotha. Thank you for doing what you do man

[@ChadsPrep]

Indeed I did and I LOVE it! Glad you find these helpful!

[@Barokimistari]

Very helpful thank you very much teacher.

[@ChadsPrep]

You are very welcome.

[@ColinDuong-ki4mg]

CHAD YOU'RE THE GOAT

[@ChadsPrep]

Thank you

[@petevenuti7355]

How does any of this work with organic batteries? Like the battery using the oxidation of hydroxyquinones to quinones? (I think it's otherwise known as the rutabager battery?) I do not see a charge change for =O vs -OH groups. Does it matter if it's in aqueous vs non aqueous solution? Is there a table of redox potentials of covalently bound functional groups in organic molecules? Would an aromatic sulphur ylide in dsmo work similar to a quinone in aqueous solution electrochemically?

[@brenttaylor8680]

awesome video!

[@ChadsPrep]

Thanks, Brent - glad you think so!

[@registeel1216]

Hello do you have a playlist for electrochemistry

[@user-ug4vr4go6o]

Chad is my hero! I wish that he was my chemistry professor.

[@ChadsPrep]

Thank you.

[@AmitMusicStaz]

Thank you!

[@ChadsPrep]

Welcome!

[@user-vl1bk9jh4h]

Thank u professor 😊

[@ChadsPrep]

You're very welcome!

[@RelaxRailRide]

Nice sir!

[@ChadsPrep]

Thanks!

[@genevieveaiwonegbe2299]

you are the best!!!!

[@ChadsPrep]

Thanks!

[@mohammadalquairi6609]

great video

[@ChadsPrep]

Thank you

[@zhanna7307]

thank you

[@ChadsPrep]

you're welcome

[@skylardean4540]

Chad is my light in the darkness,

[@ChadsPrep]

Glad the channel is helping to illuminate!

[@user-py1ch6ye4n]

Thank you this was very helpful but I'm curious if we need to cram the reduction table or it'll be given in the exam question cus idk if i can remember that table and all over the accurate values

[@ChadsPrep]

The only value I've seen students required to memorize is zero for the Standard Hydrogen Electrode. Hope this helps!

[@aiai8967]

ur the reason why im not failing ap thank you

[@ChadsPrep]

You're very welcome - Happy Studying!

[@be4nis92]

Thank you brother the first part of the video probably saved 50% of my grade on this test. My teacher explained that concept so badly 😢

[@ChadsPrep]

Glad it helped!

[@savannawilliams9358]

Hi Chad i saw on my teachers slide that the oxidizing agents are the ones highest on the list and the reducing agents are the ones towards the bottom, but here it looks like its different so im a little confused

[@max3eey]

Then those where the oxidation potentials

[@polsanisaisiddartha2124]

Nice explanation frm 🇮🇳

[@ChadsPrep]

Thanks from AZ

[@annenamuwenge9140]

at 10:50, I'm confused on why the number is -0.74 and not -0.41 because that's what's shown in the data booklet

[@TheRooflesstoofless]

GOAT!

[@ChadsPrep]

Thanks!

[@TheCharlie-mq6tx]

Love ❤from india sir

[@ChadsPrep]

Thanks from USA!

[@wanryan5431]

how do you know that the Zn is the cathode??

[@max3eey]

It's the strongest reducing agent thus it gains electrons at the cathode (cations)

[@norcyte3003]

I luv u💋

[@ChadsPrep]

Thanks!

[@daughteroftheking3220]

I'm curious if you're a Christian because I noticed you wearing a shirt with a Bible verse on it in one of your videos. If you say yes, I'm even happier since you're a fellow brother in Christ, if not that is also fine. You are not only a genius, but also a man of God, who uses his God-given abilities to help us all. May the Lord bless you with many years of good health and success.

[@michaelkelley3430]

Top two of the best chemistry channels out there! definitely helped me out alot!

[@ChadsPrep]

Glad to hear it - Happy Studying!

[@TheRooflesstoofless]

What’s the second?😅
