Today we were doing electrolysis and i asked my chem teacher about this and they said that it wasn't in the syllabus and that if they explained it it would just complicate the learning of the chapter. Thanks for nourishing my curiosity✨
Here's a tip from a fellow student to another, there is a good way to remember Oxidation = anode and Reduction = cathode. Using the phrase "an ox cared" You can know an=anode ox=oxidation and cared = ca and red which both respectively means cathode and reduction
@@mosespumpuni2631I think you might be getting it confused. Theres also a thing where electrons (negative charge) flow to cathode and positive charge flow to anode, which makes sense because anode is negative which attracts positive and vice versa. But the charge of the anode itself is always negative and cathode positive. Hope this helps.
@@mosespumpuni2631 That depends on the cell. Galvanic Cells Anodes are negatiive and positive cathodes. For electrolytic cells is flipped. The anodes are positive and cathodes are negatives. Still regardless dont pay attention to that. Oxidation happens at anodes, and reduction happens at cathodes regardless of its the cell is galvanic or electrolytic. Thats the part to remember
been staring at my chemistry book confused for days, watched the first ten minuted of this video and understood. thanks man, wonder how many people would fail chemistry without you.

Here because I'm building earth batteries. Needed to recap on stuff I learned and forgot 20 years ago. The salt bridge isn't required in an earth battery because the soil does the same job :) Thank you.
Do the electrons travel only through the wire or will a small amount travel through the salt bridge? Edit: I just found the answer on stack exchange. A small amount of current will leak through the electrolyte. To counter this modern batteries have a membrane called a separator that allows ion exchange but has a much higher resistance to combat the flow of electrons.

At 12:11 the Electrode Potential for the Oxidation of Zn should be -0.76 V not +0.76V (Oxidation electrode potential is always more negative than that of the Reduction half cell)
He is using the reverse form of the equation.....you're talking about reduction potential but the reaction/equation is an oxidation reaction...please do you get it??
You can find out that value from the electrochemical series, which is in any text book, or you can search on google. All those values have been found at SLC (standard laboratory conditions), which is using 1M concentration of the solution, 25 degrees Celsius, and at 1 bar of pressure for gases. If you have a reaction, and would like to find out the voltage produced (only in SLC), you subtract the higher E value from the lower E value found in the electrochemical series, and this gives you the voltage produced from the reaction. Hope this helped, - From a year 12 high school student.
Hello! I have a question, how can the zinc ion that left the eletrode, be dissolved in its corresponding solution, yet also pass through the wire towards the cathode? Doesnt it dissolve into the solution? Aswell, how can the anode be negative if it is loosing electrions so there are more protons so it will have to be a cation? 6:036:16
at 9:12 you said "the anions, which are known as positively charged ions", but did you actually mean to say that the cations are the positively charged ions rather than the anions?
Wait, so at 12:03 when he calculates E cell, why did he add the reduction values rather than subtract them like in the formula Ecell = Ecathode - Eanode?
Because he used the oxidation potential of Zn(which is positive), but if you calculate with the reduction potentials it's gonna be the same: 0,337V-(-0,763)V=1,1 V
I dont get the electric potential part 10:50 . If the zn soln has a potential 0.76 and cu soln has a potential of 0.34, then shouldn't the potential difference be the total voltage rather than adding it ? The vid made everything very clear. thanks for that
I just have one question. Hypothetically, if we had a Mg and Zn simple cell (one beaker) in a dilute acid, would the electrons on Mg go to Zinc or would the Mg react and reduce the H+ ions in the acid instead. I am presuming Mg would directly reduce H+ because Zinc is more reactive than Hydrogen. Also there is a bigger difference in reactivity between H+ and Mg too. ???????
Wait, I have a question. When he talks about the salt bridge during 9-10 minutes, he explains that the ZN^+2 ions move from the anode to the cathode to keep both solutions neutral by preventing the build up of charge and vice versa for the sulphate ion. When the zinc ions move into the cathode solution with their positive charge, do they then also become attracted to the electrons passing through the cathode and accept them becoming solid zinc? I did hear somewhere that what makes the salt bridge useful is the fact the ions used are stable so maybe this applies with the zinc ions but I am unsure how this makes sense if it has a +2 charge.

Concerning the salt bridge, if the zinc ions flow to the cathode side, will the copper electrode now get coated by zinc metal?
No. The zinc ions will combine with the sulfate ions from the copper side and form a salt
thanks for the brief lesson
Thanks for this
It helped a lot 👍
Please help, how do you get or where did you get the +0.76 V at 10:21?
it was just given - he didnt calculate it or anything
جزاك الله خيرا

It is the ions from the salt bridge which flow into the two 1/2 cells to maintain electroneutrality.
easy to understand👍
