I remember a few years back I had a small 3ft high pool. I filled it up, thinking I was ready to cool off but when I put chlorine in it, it started to turn yellow...I put more chlorine in it, it became orangey...then more chlorine, until the water was just red! Then I remembered that our water system had a metal problem (iron and manganese) so we had to install a filtration system, years earlier. The pipe that I was using to fill the pool was not connected to the filtration system, so the iron and manganese in the water was reacting with the chlorine. The pool lover in me was pissed, but the chemist in me was interested.

Chlorine is a silent killer for stainless-steel.

Great vid! Reminds me of my days as a boy-chemist in our basement at home. I had the clever idea to see if some of the "chlorine" used for our swimming pool would dissolve in glycerine. I put the combination in a jar and, because it smelled funny, screwed the lid on. Both my parents came running downstairs upon hearing the explosion! Luckily for me, no glass broke--only the lid blew off the top of the jar. Afterward, I had to promise to limit myself to the chemicals in the set :)

S. Holloway Therefore, does that mean if the heat wasn't applied initially, the same reaction would have still occurred, but taken a longer time?

@ArtFreak17

9 жыл бұрын

Erol Sevim Oop, maybe I should recant that I called heat a catalyst there (at least in the chemistry jargon/context, this was a misnomer on my part, much apologies)! A quick glance at wikipedia and other sources for the reaction shown makes it seem this demonstration does take quite a bit of activation energy to get it going (relative to room temperatures). So I'm not sure if that would be the case here, sources seem to indicate that it wouldn't've; if it could proceed at all, I might say very slowly. Most certainly though, after the needed activation energy is reached, more heat will likely make this reaction go faster. As an aside, many [especially organic] chemical reactions have to have specific conditions too in order to work. This is part of why high fevers are so dangerous. Enzymes, the catalysts (the kind chemistry means by that word) of life as we know it, can get damaged under those temperatures. And this is why out of control, prolonged fevers (or hyperthermia) usually leads to stuff like organ failure, because reactions aren't happening as needed.

Dr. poliakoff always has an awesome, salacious story abut an element. Well almost every one.

I'm from Salzburg! Even the river (Salzach) flowing through the city has it's name from the salt, as all the mined salt was shipped downstream on the river. The city was quite rich due to the salt deposits. A long time ago I had to learn all about the history of salt mining in school. Wasn't that interesting back then. But at least we visited the salt mines with it's huge subterranean pools of brine.

so could chlorine gas be rendered inert by passing it across high voltage corona to give it that last electron and make chloride? or will it not work because of the C2 bond?

I think it would be interesting to see the collected salts at the end, perhaps scraped onto a piece of paper. Then the different colors of the metal salts would be more apparent.

What was the wire made of that it did. It react?

What metal was the wire made of that was used to lower the aluminum sample into the chlorine gas?

what was the wire made out of that the Cl didn't eat it?

Interesting - where do you find the electronegativity number for each element? And what actually is that number indicative of? Thanx in advance

2:32 I remember making some hydrochloric acid with my dad. (This is basically a tutorial of how to produce hydrochloric acid) In the winter, we picked some big chunks of salt from the ground and then we put the pieces of salt in the bottle. We waited for the salt to melt for about 10 hours. After ten hours, we took the charger and made some bubbles in the saltwater. We did it until it turned barf green. Then we turned the bottle upside down with the cap on, and at the bottom is the hydrochloric acid.

is it STIG @ 0:13......i always thought neil had an uncanny resemblance to the stig..thanks for saying my thoughts out aloud mate. :)

what kind of burner is it that you are heating the aluminum? is it a portable stand alone unit or is it connected to a pipe? I'm interested in doing some experiments myself & I think to get a bunsen burner I would need to connect a burner to a BBQ propane tank of course also intalling an air fan hood to vent to the outside

My question now is what was the wire you used to put the iron and aluminum into the chlorine made out of?

What is the wire he hangs the metals in the flask with? Lead?

Something that I was asking myself which didn't seem to get awnsered was why were the Iron and Aluminum heated before going into the clorine atmosphere?

I think we need a new film 'Carry on Chemistry' starring all our favourite professors. With an educational aspect of course.

or the point is to get you interested in doing so yourself, taking measurements and graphing and plotting results as we did in first year university, duplicating known results and understanding reactions between different chemicals not only properties of elements - much as I appreciate this series it has really whetted my appetite for more, I only took one chemistry course in university as I was an electrical engineering major, one option is a certificate in chemistry at Ryerson University forme
