do a past paper, see what you get wrong and try figure out whether there's a fundamental misconception or if you don't get it then revise that topic. Do another past paper and keep doing the same till you're getting the top marks you can :smile:

You've recognised a possible weakness. You're going to work hard. You're going to smash it! :rave:

Hey can you guys tell me if I need to memorize the colour change during ligand substitution? I only know the hexa aqa ions colours when reacted with a base, and I only know the colour of vanadium in it's different oxidation states.

Yeah, you do you need to know the colour changes for Co, Cu, Fe2+/3+ and Al in OH-, NH3 and INXS, CaCO3 and Cl.
Hope that helps

don't forget chromium as well

I'm ****ed lmao. Do i only need to know about cobalt when it goes through ligand substitution?

guys, we've been saved I found this on student room while browsing, only need to memorize these colours :biggrin: https://filestore.aqa.org.uk/resources/chemistry/AQA-7405-REACTIONS-OF-METAL-IONS.PDF

Where in the spec does it say to learn chromium reactions?

I dont think we have to, pretty sure it was old spec
Hmm I hope not. I just know that in the practical 11 you’ve gotta know about its colour in aqueous solution, NaOH, Na2CO3 etc.......
Oh and I definitely know cobalt is not in the spec anymore

That is only the metal-aqua ions you need to know about the variable oxidation states and the colours of Ti,V,Cr,Mn,Fe,Co,Ni,Cu in the transition metal topic, you also need to know that they are formed by the excitation of electrons into higher energy shells and as they de excite they release a photon (wavelength) of a certain colour and that is how the colours are formed. Hope this helps

No way in hell that is true, I know we have to know about vanadium, and the other **** you said, but no way in hell we have to learn about Ti, Co, Ni, and Cr. Where does it say it in the spec

You understand that they often go beyond the spec right?

I mean cobalt and chromium aren't in your book for nothing. Titanium and nickel its just their catalytic activity you need to know

Dude all I'm saying is we don't need to learn colours of those irrelavant elements. You may be right about Cr, as it is an important atom.
