Golden Rain Experiment ...without water! ⛈🧪

The Golden Rain Experiment involves the chemical reaction between potassium iodide and lead (II) nitrate to form lead (II) iodide. This reaction usually takes place in water, but Dr. William Alley from Texas A&M University at San Antonio explains how the reaction can be carried out in the solid phase. #chemicalreaction #chemistry #doubledisplacementreaction

Wow! I am really surprised that they react that fast!

Safety, protection and care should be used when performing all chemical reactions

You can do a solid state reaction also with a cobalt or iron (III) salt and potassium thiocyanate. Very nice color changes.

Very nice! I just re-uploaded the same reaction in aqueous solution. I love the golden flakes you only can get with recrystallization. And you only need a tiny amount of that toxic stuff, too...

[marcochimio]

I knew the reaction, but I’m really surprised it worked in solid phase. Tres

By the title i though it was a video from ActionLab

[SzandorAdinsx]

If you look closely you can sorta see the reaction starting before the shake.

Playing with lead salts with no gloves
Is nor a good idea

[chloemccarthy]

Solid reactions will never cease to confuse me

[Pradhi_R]

Love the fact that how lead halides crystallize beautifully upon cooling down the aqueous solution prepared by increasing the temperature and letting the precipitate from double displacement dissolve by itself. Especially lead(II) iodide and lead(II) chloride.❤️love for chemistry

[oxylepy]

Thanks, that's the first time I've seen a solid reaction.

[starlighttakesform]

Wow, I didn't expect them to react this fast

[koii]

Even after just pouring, there’s a faint yellow line where the salts touch

[Samonie]

gotta love the disregard for any heavy metal safety regulations

[SodiumInteresting]

Super nice solid solid reaction.
I like the hypergolic one between PCl5 and anhydrous Na2O2 seen at the end of chemicalforce video on sodium peroxide

[yusufahmed]

Wow. Didn't know this reaction takes place with solids too!

[brucewinningham]

Pretty cool. I have seen the colors change when mixing clear Liquids but this is my 1st time with Solids.

[Johnpao]

I thought solid state reactions are imagined while reading a thesis haha...

But lo and behold! As a chemist myself! This is indeed intriguing and fascinating at the same time!

I did a similar thing on my computer using ‘paint’. I got the bucket and selected yellow then clicked on the white background. Surprise surprise, it turned yellow.
Which is about as exciting as this was

[KazzArie]

Extractions and ire would love this yellow chemistry - even more if it produced some tar
