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 5 месяцев назад

😂 thanks trxnqui

@easymodeexams33 Год назад

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.

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

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

@divinexjoy Год назад

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

@easymodeexams33 Год назад

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-

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

@IslaKrista 4 месяца назад

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
