- We show you the famous "Golden Rain" chemistry experiment - in a very new way.
"Golden Rain" is an experiment where you synthesize the yellow compound lead iodide in a very special, stunning manner. See the entire procedure, from the starting chemicals, all the way to the beautiful recrystallization of the compound.
Special thanks to our creative director Alejandra Valenzuela who gave this video a more creative aspect than we normally produce, with some upbeat music. Let us know how you like it!

The golden rain experiment is an excellent example of a double-displacement chemical reaction, a precipitation reaction - forming an insoluble compound from potassium iodide and lead nitrate. The reactants are both soluble ionic compounds. This experiment also demonstrates the effects of solubility curves.

Thanks for watching the video! Please put questions in the comments. So which do you prefer - lead or gold?
I so appreciate your content, having just discovered your website by accident and now your youtube channel. How lucky am I? Thank you so much for your labour of Love. So generous of you🙏🏻❤️
Beautiful compound
Physicists observed a strange new type of behaviour in a magnetic material when it’s heated up. The magnetic spins ‘freeze’ into a static pattern when the temperature rises, a phenomenon that normally occurs when the temperature decreases discovered the phenomenon in the material neodymium
Awesome video! Love the music
thanks for the comment Yang!
Awesome video👍👍👍
thanks for your comment Sandra!
Such beautiful crystals !
Right? They look so amazing!
Super cool! Really makes you appreciate the beauty of chemistry!
thanks for the nice comment!
This is real gold ya fake
It is real gold
Great sar ji
Now for the purple rain experiment haha
Prince is back!
This is a fantastic video, does anyone know the name of the song?
Thanks for the video, is this real gold or ? I'm learning about alchemy and i was curious
real gold color! It's lead iodide
Why don't companies only manufacture gold from lead.. why do they dig mines? .. Digging a mine is very expensive...Is bcz lead-made gold cheaper than gold found in mines or what ??
thanks for this excellent question. Unfortunately, making gold from lead is more expensive than your wildest dreams could imagine
@@ChemTalk
Will it be more expensive than the value of the mined gold?

what is that music? one-man-band-meets-rave?
It's one band rave meets man
Really interesting. Pity about the appalling choice of teen music. I had to turn off the sound before I put a brick through the screen.
Would be a great video without that annoying music!
I just about shut the video off because of the music. Consider that you have an audience of many different ages, not just of your age and musical tastes.
