From fiery phosphorous to the pure untarnished lustre of gold and the dazzle of violent, violet potassium, everything is made of elements – the earth we walk on, the air we breathe, even us. Yet for centuries this world was largely unknown, and completely misunderstood. In this three-part series, professor of theoretical physics Jim Al-Khalili traces the extraordinary story of how the elements were discovered and mapped. He follows in the footsteps of the pioneers who cracked their secrets and created a new science, propelling us into the modern age. In the final part, Professor Al-Khalili uncovers tales of success and heartache in the story of chemists’ battle to control and combine the elements, and build our modern world. He reveals the dramatic breakthroughs which harnessed their might to release almost unimaginable power, and he journeys to the centre of modern day alchemy, where scientists are attempting to command the extreme forces of nature and create brand new elements. via www.AtheistMedia.com –

Mephedrone – Chemistry Behind the Headlines 1

Posted by meme video guy On January - 24 - 2011

This video describes the organic chemistry of the ‘legal high’ drug mephedrone, otherwise known as MMCAT, meow and miaow. By considering the chemical structure of mephedrone, we try to gain an understanding of what this drug may do, and what problems may be associated with it. Mephedrone is sold as a legal high in the UK – this does not mean it is safe or non-addictive. Check out the other chemistry videos on my YouTube channel – professordaveatyork. Music by Marillion – ‘Wrapped up in Time’ from the album ‘Happiness is the Road’.

Turn Pennies to Silver and Gold (Chemistry Trick)

Posted by meme video guy On January - 24 - 2011

In a display of alchemy we turn copper pennies into silver and finally to gold. Obviously it’s a chemistry trick but still impressive. First we get 30g of zinc sulfate and dissolve it into 100mL of water. Zinc sulfate was made back in our video on making a copper sulfate and zinc battery: www.youtube.com If you don’t have zinc sulfate or can’t make it, you can also use zinc chloride. This can be made by simply mixing hydrochloric acid with zinc metal and waiting until the fizzing stops. Then we drop in several cut strips of zinc metal. Zinc metal was obtained from our video on getting useful materials from batteries: www.youtube.com The solution is heated to a boil and copper pennies, that have been thoroughly washed/cleaned, are dropped in. They must touch the zinc in order for this reaction to work. Leave it in for five to ten minutes. The zinc metal dissolves and releases electrons that go into the copper and give it a negative charge. The zinc ions in solution now redeposit form a thin layer of zinc metal. Giving the coin a silvery color. Now the smart physical chemist might wonder how this can possibly work. Overall we’re going from zinc metal to zinc metal and at first it seems like we’re missing something about thermodynamics. What is the driving force? I’ve searched the literature and there doesn’t seem to be a consensus among scientists, some claim it’s a surface free energy issue with zinc having a lower potential on copper than in free solution (at high
