"All in the Family" Properties of Halogens

[@minarostai9335]

I wish every chemistry teacher would just point out the "real life" application of elements rather than just showing students the table, increasing or decreasing ionization energies, electron affinity, and their colour only. I would definitely appreciate knowing their danger too. Anyone can google search and look at this amazing table. But how many people do actually know what the hell is it all about... No chemistry teacher has ever told me the amazing fact about fluorine being extremely killer substance! Every one of them had to teach the properties of halogens. I am really disappointed in them! A real life application of these elements would be amazing. It would really help students know and understand their world and all the materials they use every single day. Thank you so much.

We have that in Pharmaceutical Inorganic Medicinals it's a sub subject in chemistry to tell you what it's all for Maybe you can check Rogers pharmaceuticals

Additionally, you obviously can't mess with fluorine in a demo, but there are some great videos online of pure fluorine gas on otherwise inert compounds and how it instantly ignites and shoots flames and sparks everywhere. Great illustrative example without any risk and it's pretty dramatic and serves its purpose.

[@spiderdude2099]

Never realized until I was out of college how you can illustrate to beautiful purple color of iodine by dissolving it in hexane instead of water or alchohol. Really makes a dramatic illustration of the purple color of diatomic iodine without the danger of heating up to the point of sublimation which causes the purple fumes to be quite evident, but is a lot more dangerous.

couldn't ask for a better presentation, thank you

10:53 VS 12:32 , colour change in Br2 in hexane, why? Anyone knows?

[@JaspreetSingh-iu4tc]

this was great and fantastic but i would like to answer 1 simple question: why did you chose sodium to react with the 3 halogens: Cl, Br, I

[@darylcheshire1618]

The same reaction would occur with the potassium salts. In the context of the halogen experiment, either sodium or potassium salts could be used. You could even use caesium salts except they are more expensive. This is a demo on halogens and you had to have an alkali metal ion so sodium was chosen.

brilliant, i learnt more in this short video than i did in my 2 hour and 30 min chemistry class :D

[@juliaXsternicka]

Perfect! Thank you so much for that presentation.

[@backseatkisses]

Thank you! This was extremely helpful. Wish I found this video before my lab...it would've gone smoother.

[@rthelionheart]

I can talk about chemistry all day long with anyone interested in the subject. The hands-on part (laboratory) however, not so much for me. I don't need to see that first hand, I'd take their word for it. Good enough for me.

Love this presentation. It really helps be get it across.

[@muzicfreek1026]

Awesome really helpful. Thanks so much!

[@SajjadKhan-dc6df]

Very good

[@Interestingworld4567]

This presentation was awesome. Thank you

[@Mr.EricMorden]

Good video. Thank you very much for the explication. It really was very helpful

[@johnblacksuperchemist2556]

GREAT VIDEO.

[@DanniBambi]

Excellent video and presenter. Your video helped me understand my reactivity lab to better interpret my results. Thank you very much!

[@nellymanuella5213]

no problem
