Hi everyone, I'm excited to announce that I now have posters available for the reaction schemes in this video: Aliphatic reactions: rdbl.co/47y5oAk Benzene reactions: rdbl.co/41W1qQM Phenol reactions: rdbl.co/3NZc8QE Perfect for learning organic chemistry (and supporting the channel at the same time!) 👨🔬
Love your videos! What if you do column chromatography but the solution is colourless. How do I determine when to change my flask/beaker/test tube for the next component of the solution without a detector?
That's a great question! In practice, you shouldn't allow the solvent to go all the way to the top of the plate, because the spots could run, leading to inaccurate Rf values. Ideally, remove the plate from the solvent when it's about 1cm from the top. Then, use a pencil to mark the top of the solvent (so you can still see it after the solvent dries), and use this as the 'distance moved by the solvent', rather than the top of the plate.
Nice video! Undergrad chemist student here, i was hoping can you make videos covering quantitative analytical chemistry? Gravimetriy Volumetry(acid base, complex titration), and separation chemistry(chromatography, electrophoresis)?
So basically, extraction is the simplest form of chromatography? Like with a separatory funnel (well I guess it is a binary form of it, rather than a gradient).
The vast majority of what I cover will be relevant for all A-Level students. However, a very small amount of the content might not be included in your exam board, so I'd always suggest checking your syllabus to see exactly what you need to know. I hope you find my content useful!

best explanation best channel thank you i hope to reach millions of subscribers
Love your videos!

Good question! You'd need to test the contents of each test tube using TLC to check what's in there.
great video! just one question - to work out the Rf value in TLC, do you just use the height of the plate as the distance moved by the solvent?

Another good lesson.
please make some video on x-ray crystallography
As it is based on the time it takes, I am surprised that it is not called cronotography 😊

Hello sir ! Subscribed and liked :)
Quick question though
I am doing the Edexcel IAL A level Chemistry exam. Are these videos suitable for me ?
