I love jack sm. I don't see any other chem youtubers analysing past papers and making vids predicting future paper topics and making such easy to understand vids on electrode potentials and just wow so yeah bro takes his stuff seriously

[@easymodeexams33]

😂 thanks trxnqui

[@easymodeexams33]

Watch this on 2x speed if u can :) GO GO GO! btw, I left off the salt bridge in my diagrams discussing the standard hydrogen electrode since I was focussing on that half cell only, but you need to include the salt bridge between the beakers in every single cell diagram.

[@yxsm7n]

ur the love of my life thank you

[@A_a_09]

Thanks so much for this video it's so helpful! Just one Q, at 1:24:36, why is written NO3-/NO? Isn't the NO the more oxidised form so shouldn't it be written as NO/NO3-? Thanks again for all you help, a literal life saver

[@easymodeexams33]

Its the specific thing that is oxidised/reduced, which happens to be 'N'. The 'O' remains the same ox state at 2-, but N changes from +5 to +2. So +5 is more oxidised, so goes first

[@A_a_09]

@ tysm I understand and it now :)

[@arjunbhatti7324]

easy way to remember cell notation is ROOR R= reduced O= oxidised

[@ET-ek7ok]

thanks :) gl

[@x_exa_x]

in terms of remembering like what oxidation and reduction are and what oxidising and reducing agents do, remember OILRIG- oxidation is loss (of electrons) reduction is gain

[@fx22222]

25:15 why did you write CuSO4 in the diagram but Cu2+ in the cell notation ?? :)

[@divinexjoy]

Because if you slipt the ions in CuSO4, you will get Cu2+ and (SO4)2-. Let me know if that makes sense

[@easymodeexams33]

CuSO4 would be the full reagent, in case you need to name it in the exam, but the ion we are concerned with is the Cu2+ only (same for Zn2+ and other metals), we pretty much don't care about the SO42-

where do i learn fuel cells

[@imma_eatjin]

1:24:37 would you have to mention that both the NO3- and H+ can oxidise Cu and not just the NO3-? i did see something like that in a markscheme

[@easymodeexams33]

I don't think so, this question came from paper 3 2020, question 6.4, and they only mention the NO3- ion in the mark scheme (in the second column)

[@Panbxb]

1:25:00 the last equation was the product meant to be NO3 ?

[@IslaKrista]

no because it says the product formed was NO, which is a nitrogen oxide seen in the table; NO3 is nitrate and has 3 oxygens bonded to a nitrogen and NO^3- is one nitrogen bonded w one oxygen w an overall 3- charge
