Electrochemistry

[@lovapumpkina8961]

Thank you Professor Dave! Our professor "forgets" to explain a lot of the basic concepts for a chapter, leaving us confused when she goes on to more complex parts of the chapter. Your videos are brief enough for me to watch them before lecture so I can understand and visualize basic concepts.

What i struggled to learn so much time u taught it in less than 5 mins. Truly AMAZING Thank you so much professor dave

[@KSUBSCRIBERINYEARCHALLENGE]

Thanks professor you will never now how much you helped me through your short videos

[@SKgyebaek]

These videos are great when i need to refresh my memory about a-level chemistry during uni

[@sirijanthakur]

so helpful man, this chapter is filled with direct words, had missed a few definations leading to confusion, really you made it so much clearer and easier : ) thank you !

[@mirimichaely1177]

Electrons flow from low electric potential to high; the opposite of what you said @ 2:50. conventional current will flow from high to low voltage

[@jordangreaves1525]

great help

[@coastalflourishing]

For the Ecell, why didn't you change the sign of the anode to positive 1.66. The chart shows negative 1.66 for Al3+ to Al(s) which is the reverse of the anode in the problem at the end. So wouldn't you flip the sign since the reaction is flipped?

[@annamauroam]

Do you know basic math?

[@VardhanAchanti]

hello professor dave i have a doubt: cu^2 and zn^2 are same +2 right so both are oxidation . if cu^-2 is there then its called reduction right

[@yaminaboub-jo2lb]

If you fail your test after watching this , you should know that the problem is with you , not with the subject , myself included hahaha , it can't get any simpler .

[@a.sumido]

[@nirmalmishra6404]

Dave, isn't that the electrons flow from areas of low electric potential to high electric potential?(you've mistakenly said the reverse)

[@zzHackedTutorialzz]

Don't negative charges flow from a low to a high potentials and positive charges the other way around?

[@ProfessorDaveExplains]

yes!

[@zzHackedTutorialzz]

How come at 2:50 you say that electrons flow from a high to low potential?

[@ProfessorDaveExplains]

yikes, perhaps i meant energy instead of potential, i'll look into it

[@ajoykumardutta7392]

its nice to watch

[@pravinjr10]

sir in electrolytic cells we consider anode as positive and here we dont. is there any reason for that?

[@ProfessorDaveExplains]

in electrolytic cells a current is used to drive an otherwise nonspontaneous reaction, whereas in a voltaic cell a spontaneous redox reaction is used to generate a current, so it's the reverse situation in terms of electron flow

[@pravinjr10]

well explained tq

[@SachiN-Vishwakarm]

thanku sir........superrrrb explaination😍😍😍😍😍

[@retajalmalkialmalki4254]

anode is + and cathode is - not the other way round

[@ProfessorDaveExplains]

This video is correct.

[@MVC670]

Professor Dave is correct - for galvanic cells. I'll bet, though, that you are dealing with electrolytic cells. An anode is where oxidation occurs. It's mind-frying because if you want to induce oxidation at the electrode -say oxidize the electrode itself from metal to ions in solution, the basis for electropolishing - you hook up the *positive* terminal of the power supply to the electrode. Positive sucks out electrons from anything at the electrode surface Conversely, to drive reduction (reduction = cathode) such as electroplating, you hook up the negative terminal to the electrode you want to plate. Negative feeds electrons to anything at the electrode surface, such as metal ions you want to reduce and plate on the surface. I once knew a guy doing stress corrosion cracking studies on stainless steels. He told me that he set up electrochemical test cells by going through the thermodynamics and the equations, then hooking it up exactly the opposite. It never failed him.

[@tharu2360]

So if you flip the sign of the reduction potential you get the oxidizing potential for a reaction?

[@aniketbiswas9885]

anode is + and cathode is -...

[@ProfessorDaveExplains]

not for a galvanic cell! perhaps you're thinking of an electrolytic cell.

[@krapsenhelb180]

That's on electrolytic, on volatic cell we got the opposite

[@anorderedhole2197]

I am a salt bridge without an voltaic cell.

[@aminakhalid2197]

Why the charge on anode is negative

[@ProfessorDaveExplains]

Because that's where oxidation takes place.

[@merlinsmustche]

1:30 are the plus and minus signs above the electrodes the wrong way around? Cathode is negative and anode is positive

[@ProfessorDaveExplains]

No, other way. The video is right.

[@faizanshahsyed1131]

why zinc atom ionize in its solution

it doesn't, the atoms in the electrode ionize, and then the ions enter solution.

[@plamenferdinandov5083]

How is it so that near the anode oxidation takes place? Anode is positive (I don't know why but it is positive right?). So it must attract anions. And what do anions do? They accept protons. Which is equal to reduction. I can't get it please. Teachers in Bulgaria are horrible at explaining even these simple stuff and all they do is confuse students. Help

[@ProfessorDaveExplains]

No no, at the anode neutral atoms are oxidized. The electrons move through the wire to the cathode.

[@ProfessorDaveExplains]

we don't manipulate the reduction potentials when calculating Ecell, we just plug them in directly

[@carinaeizmendi1111]

I agree with jjdh911 dexter that it's easier to just think "I SUM the energies of the proper half reactions" and then flip the reduction half reaction as needed then try to remember which one to subtract. It's not manipulation; I was taught to do it that way. I try to avoid memorizing whenever possible!
