really, i didn't even get my minor (3 credits away but couldn't be organic, I loved organic too much to strive for a sidenote on a piece if paper) and I did all these experiments (except fluorine) myself. Alkalis with water, mirror, decomposing and recompising H²O .... Then it got even cooler, using H²CCl² regularly, crystalization, spectroscopy. Those were the days.
@gaussianvector20932 жыл бұрын
Did you enjoy the labs or (as I often observed) did you try to get through them as quickly as possible. I say this because I hypothesize that many remarkable phenomena go unappreciated by trying to "get it right'" or understand the math your expected to preform (very basic, but many chem majors loathe math and hence don't retain it, so in some sense they learn it all over again in chem). I loved lab and fell in love with chemistry all over again, eventually somewhat regretting my choice if major. But maybe it was the way I walked that path that allowed me to experience the experiments in a way much more akin to discovery than a required curriculum. (Especially as much of my chem was not required or even counted towards a minor and I was too far and too in debt to major at that point. I just kept taking all the ochem they would let me.)

I think the thing that makes the difference is that the properties of the groups can be explained by the valencies, and in particular the number of electrons in the outermost orbit. When I asked my chemistry teacher why certain reactions went the way they did, his best answer was 'that's the way it works'. It's so much easier to understand when you have a 'why it works' rather than just the 'way it works'.

There is another nice technique where Coloumb explosion occurs. That technique is femtosecond laser ablation and laser micromachining. It is of course not known to the general public. The highly energetic and intense laser power used causes the atoms on the surface to be fully ionized (stripping of all the electrons leaving a positively charged atom) and the resulting columb explosion vaporizes the material without heating the surrounding (it is not the traditional thinking of melting followed by vaporization).

Such a great lecture. One question that always comes to mind: HOW did the chemists at those times design and carry out their experiments (without the kind of info we have now), without burning/injuring/cutting/blowing themselves or the labs (guess there were some who did), but yet it is remarkable. Perceiving the elements with the 5 senses would be relatively painless (mostly); see (color), taste (sweet/bitter/sour), smell (odorless/pungent), touch (smooth/rough), hear (hissing/cracking), but other tests would be way more problematic especially considering dearth of equipment.

The Calcium oxide that is mentioned in this video is called 'Sunnambu' in the Tamil community in India. After mixing with water it is used to paint the walls that gives a glittering white color. If the Calcium oxide is left in open for a longer time it will react with the carbon dioxide in air and turns into a nice white powder and totally unreactive Calcium Carbonate. In fact the original 'Sunnambu' is made from collections of calcium carbonate sources found in the sea shores (many varieties of marine species known as 'kilinjal' in the Tamil language) which is burned at very high temperatures in air tight kilns known as 'Sunnambu kalavai' which turns calcium carbonate into the reactive calcium oxide. Calcium sulphate is another interesting material known since several thousand years of human knowledge.

They both work in the opposite way to a turbine blade, i.e, their objective is to move fluids by their rotating motion around a shaft, whereas a turbine blade uses the fluid's motion to impinge rotation upon a shaft. They're quite different, really.
