Toxic Golden Snow Globe - Chemistry: Lead Nitrate and Potassium Iodide Precipitate Reaction

This is an update on the classic chemistry class precipitate reaction demonstration that shows how the Lead Iodide can crystallize and make a gold snow globe. The reaction is between lead(II) nitrate and potassium iodide and it forms potassium nitrate and solid Lead(II) Iodide. This chemistry demonstration is often called Midas Magic or Golden Rain but at Beals Science, we like to call it the Toxic Golden Snow Globe! (The toxic part refers to the lead compounds used in this demonstration - do NOT try this at home!)

Great video, science communication is essential so just wanted to say thank you for taking the time to do it well.

[@BealsScience]

Thank you for taking the time to leave a nice comment! I appreciate it!

[@BealsScience]

Thanks for watching!
I'd love to hear from you! Leave me a comment and let me know what you think!
Or, maybe you have an idea for a science project or experiment? Let me know!
Thanks for watching

sir well it's been around 2 weeks and i guess the next one was scheduled at this time only. if yes please tell and try to post it as soon as possible. have a nice day.

[@mapeallan.w9390]

Awesome explanation, this video helped me a lot in my chemistry assignment 👍💯

[@BealsScience]

Thank you! I am glad the video helped! Good luck with your chemistry class.

[@priyamenon1074]

Deserve more subs❤

[@BealsScience]

Thank you for the kind words!!

[@insaneo4430]

Cool experiment! This is why i love chemistry

[@BealsScience]

Thanks!
Me too!

[@sadaf8333]

Your explanation and experiment both are at another level....I hope that you will show and explain very good experiments to us in future also......keep doing it...

[@BealsScience]

Thank you for the kind words!
I will continue making videos!

​@@BealsScienceHello, is lead nitrate smokeless gunpowder?

[@Skidz0r]

Really interesting!

[@BealsScience]

Thanks!!

[@jeremysummers-oy1es]

great video :)

[@BealsScience]

Thanks!

[@justarandomperson150]

Very cool video and very interesting:D

[@BealsScience]

Thank you very much!

[@paca_bill4863]

Very cool! Any significant issues with lead iodide stability and disposal, or will anyone who tries this at home need to call a hazmat team to their house? (That's why kiddies, we don't do this one at home!) Craig, Have a great and safe 4th!

[@BealsScience]

Thanks! Lead nitrate and lead iodide require special disposal. I do this demo with my AP Chemistry students so I figured I would show people what it is and how it is done with some of the remaining reagents.

[@arushishivhare6333]

woahhhh beautifull
😲

[@BealsScience]

It’s pretty cool, isn’t it!
Thanks for watching!

[@arushishivhare6333]

I have a doubt...is lead iodide the solid ?

[@ChickenPermissionOG]

I’m gonna do this at home.

[@TasteofIndia869]

Well this is a double displacement reaction. And elements or molecules react to get stable , so why these two compounds lead nitrate and potassium iodide which are pretty much stable leave their bonds to form some new compounds when they have already reached the ultimate goal stability?
By the way , thank you so much sir , for uploading this video. It makes chemistry much more interesting.

[@happinessallover]

Sir are there any updates on the new one?
- eagerly waiting for it.

[@BealsScience]

It’s going live tomorrow!!! The premier is set for 11:15 Eastern US time.
Will I see you?!

[@happinessallover]

@@BealsScience yeah sir obviously i'll try to be there and most probably will be.

[@nimaipatel1373]

Questions: 1) how long do you leave the solution on the hot plate/how do you know when to remove it 2) what temperature do you heat it at

[@BealsScience]

All good questions. If you can, heat it gradually by brining up the temperature slowly. The “gold” will start to move through convection and will start to clump. Then it is just a matter of deciding how big you want the particles to be-that determines time. Sometimes I go for 10 minutes, sometimes more.

[@nimaipatel1373]

@@BealsScience thanks! 2 more follow ups: 1) at 2:04 what did you add into it? 2) when you heat it, and then take it off to cool, how long does it take for it to crystalize?

[@BealsScience]

​@@nimaipatel1373 the potassium iodide solution is being added @2:04. For cooling, it starts to crystallize as pretty quickly but the crystals will continue to grow as it cools off.
Does that help?

[@nimaipatel1373]

@@BealsSciencethat helps thanks!

Is it real gold or just looks like gold?!

It is not real gold.

We need to boil this solution?????

No need to boil.
