- When Physics meets Chemistry you get coloured ions! Watch this video to find out about d-orbital splitting, and why transition complexes are coloured. Just to finish it off there is a quick look at how we can use a colorimeter to identify a compound.
8 years till he posted this and it's still helping students all over the world, gotta love the internet
and thanks a lot teach!
It ages well 🤣
just about the best series of explanation on transition metals/ions etc at A LEVEL
Cheers! Please share this channel with your friends. The more people that use it the better! 😀
These videos are so helpful thank you!! A great way to supplement and add to what we cover in college!
+James Weldrick Brilliant! I'm pleased they are helping. Like you say the best way to use them is as another review of content obtained from school or college.
You are literally my hero you make my life with chemistry a walk in the park and i hope you have the best day :DDDD
Great Video, so helpful.
Can you do a video walk through on transition metal exam style questions please??
just awesome!! I needed this
Great explaination! Thanks!
Thank you Great video!! Do you need to know the colours of all the transition metal ions?
I have a practical soon, this playlist is very helpful, thanks
+Samf Donohoe You're welcome.
I appreciated your vid brother thanks for sharing. Hi from Montreal.
Really good video....well explained as well....thank you pls continue to make aqa chem videos.
Thanks!
Thank you this lesson, I understood this much better
+obedosei1 Brilliant! Yes this can be tricky bit of chemistry! A good topic if you like physics! ☺
Really Helpful Thanks for your help.
Just would like you to tell me whether I am right or not.
So, Once the transition metal ion is bound to the ligands this causes the -d- orbitals to split in the metal ion into lower and higher energy levels. Electrons are able to migrate between the split d orbitals.So, an electron can absorb energy of one colour of light of the right frequency and get promoted from lower energy level to another, and thus we can only see the combination of colours that are not absorbed, right ?
I love it when chemistry and physics link together 😊
Heh! So do I.
How can u tell if a ligand will substitute the ligand in the complex ion and the resulting complex ion? What's worse is the colors.
Do you have to know the equation if you do OCR ?
Hi Sir, important question my school writes 2 boxes over 3 for the octahedral and 3 blocks over 2 for my tetrahedral complex. Does it matter? I do the AQA syllabus btw. I think you mentioned in the video it dosen't but I wanted to make sure nothing else changed. Thanks
Is this specific to AQA A-level chemistry? You are brilliant thanks!
No although it is suitable for AQA. Most boards have similar content.
Pls I need PDF file explain this curve
The chrome appears green because it absorbs the red color
What happens if we drop it a blue light only
Help me out! Only the audio could be heard...the video is going totally blank.
Hmm don't what is going on there. The vid definitely works. Maybe if you change the browser then the video may play.
do you need to know this for OCR A?
Yes a pop up box says which you need to know.
The symbol for frequency in E = hν is not the English letter "v", it is the Greek letter "ν" (nu) :)
Yes that's right. This is shown in the vid too.
Good Vid once again. However, I have one point I need you to clarify if possible. My teacher told me that 3d-orbitals splitting to 2-3 or 3-2 is related to the shape of the complex the latter being octahedral and the former being tetrahedral and that I should know this.
+Uks bridge Thanks very much! Which specification are you doing?
A Level Chemistry by Allery Tutors AQA
+Uks bridge No not required. Just an understanding that you get d-orbital splitting and that this allows electrons to be promoted to a higher energy state. You need to use E=hv too. Hope this helps.
A Level Chemistry by Allery Tutors Thank you! Much appreciated
I don't think this is on the OCR spec either.

Not me watching every video to try pass at least one Alevel
lesgoo me too
