AQA A-Level Chemistry - The Halogens (Gp. 7)

This video runs through the halogens section of the AQA spec. Note that it does not cover the trends in boiling point and electronegativity.

Due to the length of the video, the following markers can be used to take you to the named sections:

3:57 - displacement (oxidising power of the halogens)

13:43 - formation of bleach

16:26 - chlorine and water

20:22 - halides as reducing agents

23:23 - reactions with sulphuric acid

34:19 - testing for halides

bro made this when I was in year 5 and 8 years later i'm here in year 13 using this MAD

"I chose potassium because... I like the look of the K"

I might have to apply the 'formation of bleach' to a use other than cleaning, if my exam this afternoon is as bad as the specimen papers.

You're an absolute saviour man.. I find watching these so much more beneficial than reading the books! Thank you

For those of u who wants to know the sulphur one then this is the equation
6HI + H2SO4 ----> 3I + 4H2O + S. Which is yellow solid

Your videos are so concise 👍 I can't imagine how your lesson must be like. Do you manage to do the entire AS course in one term haha

[bensonthomas]

It's odd how I don't get this topic for a month, I spend hours reading through the text book and I still don't get it. I then come across this video and get it instantly! Thank-you!!

[MHAN]

Thanks so much! Actually understood this just need to keep repeating it to get it in my head! Its funny how my Chem Teachers needed 3-4 lessons to explain this and even then they rushed through it, I didn't understand barely any of it...But you explain it perfectly in 40 (which is 5 mins earlier than a single lesson in my school) making it easier to understand. Ty once again!

This bit is GCSE on STEROIDS. This guy is my hero

[abzlife]

not watched any of the videos yet  , but just wanted to say that we appreciate you taking the time out to produce these videos, very grateful

[joshteale]

"gcse on steroids", helpful vid thanks dude :)

[samanthajob]

Suddenly YouTube is full of scientists rather than haters, thanks

[bodooraljurf]

Honestly, i have no idea what i would do without your videos. You are Literally saving my a levels.

[GILDGAMINGGILDGAMING]

Exams in two weeks, none of this topic stays in my head

[peonyeffin]

The way you said cleaning at 14:38 just made my day, (thinking about all the poor unfortunate A level students who have never cleaned anything :') )

[ismailumarji]

Very useful to watch the night before the exam to pick up some of the small details, thank you!

[deltius]

great example of why this guy is a better teacher than my teachers: if my teachers had just called it formation of bleach i would've remembered it from the start

[aavashism]

Thank you so much, sir. You don't realize how much of a favour you're doing by spreading education in the world. You're literally changing the world. Thank you so much! I'll be done with my Alevels in OCT/NOV, but never making such informative Alevel vids, I assure you, it'll be a great help for the next generation of students as well!!!

[biancasoo]

The'GCSE on steroids' tho.... Great video!!!! Helped me a lot since I have no idea what my lecturer is talking about.

[rayyankhan]

This video was helpful, I can't thank you enough for this, you are truly the best chemistry teacher ever
