is this for the aqa syllabus, they don't specify in the spec about knowing about chromium, copper and cobalt. They do mention Vanadium though. Thanks for the video !
thankyou very much. you explain everything of the topic and it would be great if you solve a hard past question after explaining the topic so that the question includes all the crucial points of topic.
+Shakeel Ahmed Thanks very much! I have done videos on exam questions. Here is a video that includes transition metals ruclips.net/video/oRcJMGkTDW0/видео.html many more to follow too.
THANKYOU SO MUCH! Really appreciate it :) are you going to be any on ligand substitution? and also I can't get my head around electrode potential calculations, whether it's feasible or not because there are SO many ways of doing it and it has totally confused me. I really don't want to lose crucial marks in my exam. Thank you once again :)
Sonil Zaki Yes, more transition metal videos to follow. This will have to be next weekend due to work commitments. With regards to feasibility I would look at the anti clockwise rule to help you with this. Thanks!

This is no longer on the AQA syllabus 2019
If you turn your auto exposure off, on your camera it should stop the constant lightening and darkening of the video
Thanks I will look into it. It's a HD Logitech camera so there should be loads of help out there on the web as to how to do that.
Don’t think this is for the new spec, as the aqa chemistry guide only mentions Vanadium

@@AlleryChemistryWhat camera do you use to do this video? Can I please have a picture of the setup?
Hello! The new AQA spec says the Cobalt chemistry is no longer required as it used to. Is this true? Please answer if you know this
It is true, yes

A level Chemistry Revision Tutorials by Allery Tutors Thanks, I'll be waiting.
you da real mvp 😉
Thanks! If I'm honest I had to do a google search for mvp. Ha!
So how does the dichromate to chromate equilibrium exist naturally if you have to add OH- for the reaction to occur?
is this in the new spec?
you're a legend thank you!
When you react "chromium" with oxygen, how do you know whether Cr3+ is to be used or Cr2+ ?
So helpful :) - please make a video on entropy and Gibbs Free energy if you have the time
a legend...
is this needed for aqa? it only talks about vanadium
life saveeerrrr
I thought if u add acid the equilibrium should shift to the right?
Why chromium doesn't exhibit + 1 oxidation state , it contains only 1 electron in 4s orbital ?
My textbook says Cr2O7 (-2) + H2O 2CrO4(-2) + 2H+
Why is it H2O and not OH-?
Cr2O72- has to be dissolved in solution hence the reason why we have H2O
WTF THEY NEVER MENTIONED THIS AT SCOOL
