EDEXCEL Topic 4 Inorganic Chemistry and the Periodic Table REVISION

[@jwyz26]

I cant believe you’re spoon feeding the information without missing a single bit from the spec out, this is so incredibly useful thank you so much you’re a legend

[@a.human.]

You deserve millions of subscribers! your videos are the best and have helped me so much during my journey as a self-taught A level chemistry student. I don't know how will I perform in exams, but if I pass or do well, full credit goes to you... so thank you so so much for making these videos. I really appreciate all the hard work.

[@ismailabdullahi560]

watching after 4yrs and still feels it helps very much am a student who is reciting unit2 after 3 months of not seeing chem.I don't know how to thank you but still wanna say thanks for assisting us in busting our grades

Wow! what a great video, the amount of effort that has gone into this is very apparent. Great job at explaining things, and the small mistakes, whilst apparent, are understandable, as even the textbook sometimes gets things wrong. One thing I noticed is that the textbook has a highlighted box explaining that the acid formed by reacting Hydrogen iodide with water forms Hydriodic acid rather than Hydroiodic acid, which you put in the video. I hope this helps any future viewers, although both names are listed in the wikipedia article. Great stuff though, I have subscribed for more.

Love these Revision videos, they are super helpful!!!! Will you be making equivalent videos for Edexcel Year 2 Revision?

[@nefeligeorgiou7016]

Great work! Very clearly and thoroughly explained. Pleasant to watch and perfect for revision. Thank you

[@ganyahgoldstein1331]

thank you for all these revision videos

[@MegaSuperDevna]

Hey Chris! Great video! At 13.11, you mention group one carbonates are thermacally stable, I don't understand why Li is the exception, all the group one carbonates decompose to form an oxide and CO2.

i really appreciate your work .it was such a good video though i didn't understand the last part.thank you so much

Hey Chris! I watched all your Edexcel AS Chemistry vidoes before my IAL exam this week. Had my Unit 1 IAL day before yesterday and thanks to your videos, exam went Good! Unit 2 is day after tomorrow. Was wondering if you could give any recommendations for the Unit 3 Lab skills (its on the 23rd October)? And also, when are you planning to put up the A2 Edexcel syllabus videos? Cheers!

[@aksharkotecha1855]

thanks for the A*

[@AlleryChemistry]

Congratulations! What a result!

[@ayeshah4138]

Will you soon be doing these same videos but for year 2 (A2) as these are super helpful but I am moving on to A2 now and was wondering if you have these videos for that 2nd year course

[@AlleryChemistry]

That's the plan!

[@hamimahmed5459]

There is a mistake in the testing thermal stability section the test for nitrites is labeled as test for nitrates

[@anonymuslibrarians]

This was super helpful, thanks!

[@swaranbains8326]

33:33 when the halide loses its electron I am confused as to why it becomes negative- when it loses an electron I thought it became an anion

[@Bash_the_Bash]

It is negative before losing the electron. In its regular non-ionic form a Halogen (atomic form) will try to gain an electron to become more stable as a Halide (ionic form), and a so if a halide ion loses an electron it just goes back to zero charge as a halogen. Halogen atoms don't form anions. To answer your question simply the green box is referring to the ion before losing the electron not after.

[@karsondhakal8139]

Hello allery chemistry, May I ask how do you revise for A level Chemistry and how can I ensure that I can get an A/A* in chemistry? Thank you

[@MegaSuperDevna]

Hello Chris, at 39.02, you talk about halid ions with sulphuric acid. This is not on the edexcel syllabus.

[@ahmedibrahim9082]

Amazing !!!!

[@uouuou-fh7vm]

Sir, can I use this for IAS edexcel syllabus?

[@AG-ql1sy]

35:19, i think you copy and pasted the reactions in the green box and forgot to change the halide ions

[@taya1772]

hello sir,I would like to know if the function of barium and mg(oh2) is part of the spec as in the textbook it’s says barium metal-outlines but in X-ray scans and magnesium hydroxide is used for indigestion medicine

[@charleshierner2024]

at 32:26 you say that H3O+ is a 'hydroxonium' ion. is it not 'hydronium' ion or am I mistaken? also is the ClO- and H3O+ ions the molecules that kill the bacteria or just one of the two? is it because the acidity of H3O+ causes the pH to fall and thus kill bacteria?

[@reemb9866]

Smashing it mate

[@supnation]

its edexcel alevels right?

[@AlleryChemistry]

Yes that's right 👍

[@sultanafahimaazhatunnisa5066]

really helpful

[@sara5001]

what about iodine/thiosulfate titration ?

[@mrfreerunners1]

would you recommend edexcel or aqa for a level chemistry ?

[@AlleryChemistry]

When I was teaching, I went for AQA because I thought the structure was better for students to remember, however, it really is personal preference. Suppose there are more revision materials for AQA too, so it makes it easier for students to revise.

[@mrfreerunners1]

@@AlleryChemistry the fact that aqa has more resources online for private students helps me decide :)

at 5:20 you said magnesium is being oxidized but its being reduced xD its fine tho ur videos are making me pass so thx

@Timon Fullbrook Exactly

What you have to know about repulsion of outer e- from inner e- for ionization energy:)
