You didn't explain well why Cu has +ve reduction potential. If Cu²+ is 3d⁹ which is undesirable then it should be more negative but it's not

[@manvendrarathore4748]

3D9 is undesirable, whereas 3D10 4S1 is more desirable, it wants to acquire electrons as the oxidized state is less stable than reduced state, hence REDUCTION Potential should be positive....which it is

[@praveenshetty1079]

One of the best videos on this topic

[@srirammurali8820]

The explanation really helps me during the time of examination . Thank you very much mam.

[@alokjaiswal_1]

Best explanation I had ever seen

[@nxmxn661]

why is E(fe3+/fe2+) positive even though Fe3+ is preferred due to d5 configuration ?

[@NavneetKaur-iz3hp]

Simple and easy explanation!!!

[@navyblueskiess]

Thank you mam.

[@Funnymemes2k]

Well explained, thanks!

[@firemotivationwallah]

Thanks 😊

[@Bluemoon325]

5:59 if e is -ve then change in free energy will be positive so does that mean that the reaction is non spontaneous?

[@vachan-maker]

yes change in gibbs free energy=negative nFE

[@DZ_DasherKTB]

isne poora concept ulta samjhaya hai, koi or vidoe dekh liyo bhai peper se pehle

[@pinkychavda4049]

Thank you very much

[@rushdamariam3860]

that was amazing

[@Mgusain18]

Best ❤

No voice? Or its my fon problem?

[@navyblueskiess]

Your phone might have a problem cuz mine's working fine .

[@imadkhan4456]

it's phone not fon

[@sonorousgaming7202]

It is offensive to correct spellings all the time. I mean, it is assumed that they used a short form "fon" to spell the word "phone" and they are aware of it.

[@anonymous20060]

Your fon problem

[@Sirik343]

English problem

[@chetanbondre4055]

Mam Hindi mai bola kro na

[@fequalsmalol]

thank you very much maam
