In this video, we look at filtration and crystallisation, which are both examples of physical separation techniques. First, I discuss the substances that can be separated using filtration and how to set up filtration apparatus. We then look at which substances can be separated by crystallisation. We also explore the use of state symbols.
This video is based on the AQA spec. If you are following a different exam board then you should check your specification. The Amazon link above is an affiliate link.

After watching this i now feel like a genius and i want to tell you i lov you you dad
wow
Meet our saving grace of a teacher
Thank you for existing, good sir and also love the intro
wow! i thought all GCSE vids were from years ago! thank you for everything you do :)
Thank you for saving me for my year 11 mocks in november
Exam tmrw and got few hours to revise, i think this man will save me
you are brill, thanks pal
legend got mocks in 3 weeks u savin my grades
Sir is the sodium chloride solid crystallization the mixture we need to remember or can they ask about any elements?
Hey sir. Your channel has helped me in regards to revision. I like how you condensed the topic down to just what we needed to know, as you yourself said: no waffle, just the facts. However, there's something I need to say. Can you please describe the diagrams you put on screen. I'm blind so it would help to have someone describe the diagrams so That I can visualise them in my mind. Thanks a lot for all you do for us,
MA
thank you so much
Sirthese videos are very helpful is I just started year 10
Do you have any videos on properties of materials. Gcse
I need you as my teacher smh my teacher marks my homework as missing when my work is literally right there 💀
Hi sir I hope you are well your videos are great and help me a lot. I wanted to ask so far how much a level biology content have you covered
I've covered just over 50% so all the Year 12 content and a bit of Year 13. I expect to have all the Year 13 content covered by the end of 2024, early 2025.
So around mid 2024 you will cover all of year 12 content for biology
will this video work with edexcel? Because I am learning this in edexcel chemistry too
Yes there's a massive overlap between the AQA and Edexcel GCSE specs.
Hi sir, I thought we needed to know more steps for the crystallisation method (e.g. filtering the solution, using an evaporating dish, then heating it gently and finally patting them dry or leaving them in an oven)? Will it not come up as a 6 marker method?
Hi. You are describing the required practical "Making a soluble salt". There is a video for that which covers the whole method.
thank you 😅@@Freesciencelessons
Thanks
Hi sir, what playlist is this GCSE video under? Thanks for your incredible work I can't thank you enough :)
This is in "GCSE Chemistry Atomic Structure and the Periodic Table".
exam board?

Hi sir i was just wondering if all your videos so far for a level chemistry have covered all of the year 1 content, or is there still some year 1 content that you haven't covered yet
I have finished all of the AS Chemistry videos so the content should be covered. However, I would recommend that you check your spec. If there is something that you think I have missed, please let me know.
Hey sir what is the best way to memorise the charges,names and formulas of common ions since they don't give them in gcses now
they give you the periodic table in the chemistry exam
They give the periodic table, just remember how much electrons the element needs to lose or gain to make the outer shell more stable
Question: do you edit these videos by yourself?
guess iv always wanted to know so i thought id ask this random question hahaha
thank you for these videos they are a lifesaver
Sorry for the late reply. I do the whole thing.
Hi sir I was just wondering by when do you predict you will finish Yr13 biology and chemistry because that is what i an doing next year.
I'll have finished Year 13 Biology and Chemistry by mid-2025.
Have you done every gcse science? Thank you so much for your lessons, they have helped me get an 8 in my end of year examinations, hoping for a 9 in each for my mocks!

Hi Sir for the exam can you just say for crystallisation:
If the solution is left for a few days, the water will evaporate leaving behind crystals?
That's correct.
