U can try remembering it like this
Red Cat- Reduction at cathode
An Ox- Oxidation at anode
"GaAn(-Ve)", (prounounced as GaAnVe)- galvanic cell anode negative (suppose if you remember this, u can write galvanic cell cathode and anode, cathode of electrolytic cell too)
U are so good 💯 u want to help students but they don't care they can't even praise ur hardwork by liking it

1:37:45 The cell reaction may be split into two half reactioin as:
Zn→Zn2+ +2e-
(oxidation half reaction)
2Ag+ +2e−→2Ag
(Reduction half reaction)
Here, we are given standard oxidation potentials as
E∘Zn, Zn2+ = 0.76 volt and
E∘Ag, Ag+=0.80 volt
We need oxidation potential of zinc electrode but reduction potential of silver electrode.
Reduction potential of Ag electrode=-Oxidation potentil of Ag electrode
=-(-0.80 volt)=+0.80 volt
Std. EMF of the cell=Std. oxid. potential of zinc electrode+Std. redn. potential of Ag electrode
=+0.76+0.80 volt=1.56 volts.
Correct but your reduction rxn has a small mistake i.e
2Ag+ + e‐ -> 2Ag ( only one electron is used to neutralize silver here)
@@anbttlno you’ll need two electrons to neutralise two Ag ions. Otherwise charge won’t be balanced on both sides.

A short cut to remember cell representation of Daniel cell ABC where,A stands for anode,B stands for salt bridge and C stands for Cathode .
One more short cut for remembering is An Ox I.e, at anode oxidation takes place and Red Cat where at cathode reduction takes place .

Super invention
Red cat - reduction at cathode
An ox- oxidation at anode

N se negative, C se cathode, R se reduction.
Don't mind I just wanted to make it more simple. 😊

Mam plz give it a correction in 1:31:54
The correct order will be Ag
Why???
Actually the answer is correct but Ag>HG> Cr>MG>K Because reducing power means oxidation potential
@@MaryGrace-q8g yes, reducing power means ''tendency to oxi the other compound'' that is LOSS OF ELECTRON which is OXIDATION
@@MaryGrace-q8gmam changed the ques to reducing potential not reducing power...!!

Ques. Calculate the standard emf for following reaction.

Electrode potential of Zn & Ag are -0.76 V & 0.8 V resp.

Mam at 1hr 29min....that sum answer u did wrong....reducing power means that should have higher oxidation potential....so answer is k>mg>cr>hg>ag ....
Thank u so much mam...I am weak in this chapter...u make it strong....that was a slow crtion mam....the session is awsm...💥💥
You are right dude
Yes, you are right but then mam changed it to reducing potential, that's why the answer was opposite. However, according to the actual question you are correct.
Yes u r right bro....

anyone for 2025
This lecture is enough for back benchers .
Than, What about for toppers..... ?
You got me bro 😂
Why do we take only H electrode as standard one, why any other element electrodes?
It is used as hydrogen has been used conventionally for many purposes and why one should not choose an element which is on the top of a table .
Although this selection is totally arbitrary and now there are various electrodes like silver and so can be used for the same .
Because we assume hydrogen electrode potential to be zero...and because it's middle in reactivity series and is also inert...hence used
When beauty talks - views😂

Zn(s)|Zn2+(aq)||H+(aq)|H2(g)|Pt(s)...........................mam answer for homework :))))))
1:58:50, i dont know why but I'm not able to understand this concept. In the starting of the lecture we were told electrolytic cells have positively charged anode and negatively charged cathode and vice versa for galvanic cell... Then why is it opposite for electrolysis? Why does electrolytic cell is said to have positive cathode and negative anode?????
Because electrolysis cell made when the chemical process done due to electric current so the charge opposed
