Transition Elements 6 - Ligand Substitution

Demonstration of some of the ligand substitution reactions required for the OCR A Specification

[@aminanaveed8432]

YOUR THE BEST, ENDING THE NIGHT BY ACTUALLY UNDERSTANDING THE EQUATION/COLOUR CHANGE, INSTEAD OF JUST MEMORISING IT FOR THE SAKE OF MEMORISING IT!! truly amazing

[@H1-NMR]

I can’t disagree what a way to end a day

[@wafa2075]

Amazing demonstration! It's really helpful to see actual chemicals alongside their theoretical formulae. Thank you!

[@pjt5227]

Thank you very much for including additional material. I'm a mature student with no prior exposure to chemistry except for GCSE (a long time ago!). I'm currently writing a lab report on coordination compounds and this has been very helpful in explaining all the stuff I was meant to know before enrolling. As everyone else in the class has studied this topic to a certain degree, we've had a very fleeting introduction. I'll see if I can work through all your videos and give em a thumbs up for the help.

[@Letik3x]

Thanks for making these videos available for everyone, I really appreciate you! Thank you sooo soo much

[@yungaagigglez12]

ur such a great teacher thank u

[@zannatul23]

+Miss Said i totaly agree mr said

[@hxvoc_7708]

great video

[@sounad3736]

I'm sooo thankful to you! May God bless you❤

[@MaChemGuy]

You are so welcome

[@ummewaseem5983]

I actually can't thank you enough.

[@deuterium4.028]

thank you

[@M7RAA]

thanks

[@milanbatinica244]

Amazing vid!

[@tgdhsuk3589]

5:20 i can totally see that being in a Ka question about weak acids and so on with out giving us hints... or worse buffer solutions and partial neutralisation faq

[@10mshah]

Really useful videos, where are the videos for the new syllabus with more reactions?

[@brooklynrobbo764]

If I add excess NH3 to cobalt ions do get the same equation as with copper ?

[@henersinsane]

When I say this I mean like this, how do you know that it is [CU(OH)2(H20)4] 2+ and not [CU(OH)4] for example

[@ER-wk8um]

Thank you for your videos. They are really useful. Could you please let me know where the (extra) ligand reactions for the new OCR syllabus video is?

[@ER-wk8um]

Thank you!

[@MaChemGuy]

Elena Rasool You're welcome. Will be making another one where I explain the reactions. In the meantime here's the link to my video index. bit.ly/2hqSBeD

[@henersinsane]

Hey very quickly do you have a list of all of the substitutions required for OCR and the colour changes and also how do you know when for example in a substitution it forms [Metal ion, (X)4, (Y)2] or just simply [Metal ion, (X)4] etc?? If that makes sense! This stuff I really need to learn tonight!!! and is there an easier way to contact me e.g. through Google Plus or something??

[@nurlatifahmohdnor8939]

What is T.M. write full. I have forget so many. Tq.

[@nurlatifahmohdnor8939]

CuSO4 colour. Cyan.

[@ahmedabdi6941]

Why don't Ligands substitution form insoluble precipitates and they form aqueous solutions instead?

[@soroushpaziresh3271]

Legendary! just one question, how comes Cl- ligand can be present in an octahedral complex ion with a coordination number of 6 if it's too large? for example in [NiCl2(NH3)4]+?

[@MaChemGuy]

Thanks. Those NH3 ligands are small enough

[@mrhalol3]

Is there any way to work out what is small enough etc. or is that too complex for the syllabus/exam? Thanks

[@MaChemGuy]

+hwyt too complicated-just stick with those you're told about

[@mrhalol3]

+MaChemGuy okay, thanks. do your videos go over all of the ones we need to know, or just the theory needed to understand the others?

[@MaChemGuy]

+hwyt I've covered everything in the specification. They do like you to apply your knowledge to unknown examples too as I'm sure you're well aware

[@ellainett5437]

Is this still the same in the spec OCR? Or is it different now?

[@MaChemGuy]

The cobalt reactions have gone and there's now manganese reactions. Here's the link to my latest one kzbin.info/www/bejne/fqOkZ42AgcqDqqM

[@ellainett5437]

MaChemGuy thank you so much! 🙏🏼

[@MaChemGuy]

@@ellainett5437 No worries

[@ummewaseem5983]

Could you please make a quick video on kstab when you get the chance? thank you for everything

[@MaChemGuy]

Will do! :)

[@ummewaseem5983]

Thank you :)

[@sharmeenvohra724]

Hi do you have a word document of all the equations we need to know with the colour changes because there are many equations that are not in my textbook/ notes that are in videos. Thank you

[@hxvoc_7708]

you have to take into accoun that those are from the old spec, so some arent in our current spec anymore

[@ummewaseem5983]

is the OH- in (CU(OH)2(H20)4) 2+ acting as a ligand or is it ionically bonded to the Cu 2+ ?

[@tgdhsuk3589]

ligand
