[@mpumiiee6642]

Red(uction) is at Cat(hode)=Red Cat
An(ode) has Ox(idation)=An Ox
That's how my teacher taught my class

[@kevinmathscience]

Love it!

Hello from turkey, this series has done a much better job at teaching me the subject than all the other ones i could find in my motherland. Really concise and straight to the point, but i wish they were a tad bit more organised so i could know when to take notes rather than relying on improv.

[@serdarbilmez9050]

You are right and your English impressed me

[@zee7718]

Absolutely, it's not easy to make notes when watching kev videos he's sort of disorganized and whatever, but he's good

[@siyamthandambelu9607]

LEO means Losing electrons is Oxidation
GER means Gaining electrons is Reduction

Or OILRIG

my guy......ur an absolute G.....best ever......no teacher teaches me the way u do......thanks a lot.....my teacher just confuses me more and more

[@kevinmathscience]

Pleasure!!!

[@thofeeqwahab07]

RED-CAT (reduction at cathode), AN-OX (oxidation at anode)

I wish you were a teacher in my school honestly 😂❤

if I discovered bro last year I would've been in university right now

[@imagination944]

Yohhhhh you failed vele

[@LebohangPoho]

@@imagination944 well I didn't fail but my marks aren't that good

[@brenttallon]

OA are vowels oxidation at anode RC are consonants reduction and cathode.

Thank you so much! All the best to you :)

sir, you are a legend
thank you

You're welcome!😁

literally a GOAT, passing math and physics because of this guy .

Looks like an interesting informative series!

Why was Copper ( CU) in our galvanic cell being reduced yet in the 4B table it is below zinc and should have been oxidising ( giving out electrons)?

[@breakaliciousbinge6067]

We used RedCat and OxAn
RedCat means REDuctions happens at the CAThode and OXidation happens at the ANode❤

[@jessicaiyera]

Thank you, sir! ✨👍 Very helpful ✨

[@kevinmathscience]

Only a pleasure Jessica! Thank you.

[@dawn4030]

too good ! are you gonna do electric circuits ?

[@kevinmathscience]

Will do my best :)
You can try my 7 day course which does have electric circuits:

Hi Kevin.How do you know which way the arrows should go?

Hey Kevin can you please do a video on electricity and magnetism. I just fail to understand it. 😭

[@kerimoodley1178]

Sir, how did you know which copper to choose from on the table? There is another copper with 0,16V as it’s voltage, so why won’t you use that?

[@seanwortley2485]

At 1:39 he says that the system will react by "taking the BEST oxidiser and the BEST reducer". So technically yes the copper with 0.16V is a possible reaction, in this system it will not happen, because the copper sir showed is a better oxidising agent (you see the arrow on the left side, pointing down). So in any system with multiple possible half reactions in a cell, the half reaction that is the BEST oxidiser or BEST reducer will always happen over the rest. i hope this helps :)

[@kevinmathscience]

Thank you! Just to add to this: the question used a galvanic cell with cu+2 and Cu. So we use that one. If the question used Cu+ and Cu, then I would have chosen that one.

an ox makes a red cat, i try remember that when when choosing cathodes and anodes

Hey kevin
Quick question...so why did the CU+2 win instead of the cu ,when why did Zn win instead of zn+2 ??

Can u plz do counting principle
