I would highly recommend this video and nothing else. If you want be spot on with transition elements, do watch this video and then do exam questions to apply your knowledge

this was so so helpful, I didn't understand this topic at all until I watched this video - thank you SO much

Really great and understandable session, thanks!!

he saved my life this chemistry video is brilliant!

this is such an excellent video thank you for all your effort! well appreciated:))

16:05 - the spec does say Cu2+ catalysing the Zn reaction but the first reaction you meant Mn instead of Cu :)

SIr, Cr3+ solution is violet not green, and Mn2+ sol becomes a light brown ppt not pink according to the ocr a book. pg 152. Thank you for your videos they really help!

Re Cr3+: technically it is violet but in practice, it looks green. I think OCR MS accepts both green or violet because they cant argue with what you would see in a lab.

Mn2+ itself is light pink, Mn(OH)2 is the brown precipitate

Thank you so much !

Amazing video thank you! At 27:51 i think Ethanedioate has a single bond between the Carbons. And at 50:49, Fe2+ to Fe3+ is purple to colourless solution. Or perhaps OCR is lenient with colours? and the balanced equations for Fe3+ to Fe2+ and Cr2O72- to Cr3+ is: 2I- + 2Fe3+ > 2Fe2+ + I2 (pale yellow to brown solution), and Cr2O72- + 14H+ + 3Zn -> 2Cr3+ + 7H2O + 3Zn2+

At 51:31 the Fe2+ was not multiplied by 2 on the RHS :)

doesnt ethanedioate have a snigle covalent bond between the carbon atoms

this really helped, thanks

Chromium is violet when in aqueous solution no?

at 21:54 isnt Mn2+ light brown with OH and NH3

really helpful video thanks! I think in my textbook it says the ethanedioate doesn't have a double bond between the two carbons tho!

Yeah you’re right carbons can only form 2 bonds anyway

Thank you so much! All is not in vain! By the way, do we have to memorise the Complex Ions Solution Colours table?

Great👏

are u sure we have to know all these colours? I have the PDF file from OCR "colours of inorganic ions" and it barely has half those ions

Hi sir, the CGP book says copper goes from ‘pale blue solution to blue precipitate’ , but in this video it’s the other way round saying that the precipitate is pale blue and solution is blue. Does it really matter or is there a mistake somewhere 😵‍💫🤔. Thanks

It goes from a pale blue solution to a pale blue precipitate. Then adding excess NH3 makes it a dark blue solution

@mistyz6347

Copper (II) ions (aq) form a blue solution, and Copper (II) ions + aqueous OH- ions form a pale blue precipitate.

I thought cr3+ in aq was dark blue

thanks i got my exam at 09:00 today, wish me luck

hey big man, Im sorry to infringe on ur GOATmanship, but at 51:35, when multiplying the half equation for the oxidations of Fe 3+. you missed a balancing number in the final equation. Other than that, keep up the amazing work u absolute GOAT.

Allery Chemistry at 51:29 why is Iodine being oxidised isn't it gaining electrons ?

wait but from 2I- to I2 thats losing e- right as its getting less negative so its oxidation
