- It's not just student that have to do tests! This video will look at the very common chemical test of halide ions using silver nitrate solution. Watch out for those pesky carbonate and hydroxide impurities though!
I couldn't understand this practical previously but now it's so clear. You are a really good teacher.
I tasted all 4 of them
Ghost572 Hmmm. Don't think they would do you much good.
Like the shirt 😆
Sophie Dennison Thanks. A Christmas present from the wife. She knows me very well!
I know the test really well but I get confused when I am working out their questions
Hi! Great video!
Would the test work if the Nitric acid was added after the Silver Nitrate?
Raahim Aziz Thanks for your comment! It should really be added prior to the addition of silver nitrate as it will react with any impurities that could form a precipitate when silver nitrate is added.
the shirt is amazing!!!
Hah cheers! Christmas present, they know me too well!
lol that shirt is everything. Thanks for the video!!
No problem!!
Great video as always!! For OCR A Is this module 3, chapter 8.3 or 8.2?
the halide test is mentioned in 8.2 but in 8.3 it indicates in what order you should do it in
Well explanation
Great video
Thanks very much!
i get confused in questions about when its talking about the best reducing agents or oxidising agents
and whether a Cl2 atom or Cl- ion is best?
Are Cl- ions best reducing agents - the ION
and Cl2 worst oxidising agents - the ATOM
Oxidising agents gain electrons so Cl2 is a good oxidising agent. It can accept electrons easily. Reducing agents are lose electrons, I- would be the best reducing agent as it loses it's electron more readily.
Makes so much more sense now thanks :)
That's a rlly great t shirt
