Making High Quality Prussian Blue With HCN Gas #chemistry #cyanide #donttryathome #pigments

I react chunks of iron covered with sodium potassium cyanide (a byproduct of the sodium potassium cyanide synthesis) with ~6M HCl to produce very fine particles of Prussian Blue. The acid reacts with the cyanide ion to produce HCN in solution. The acid also dissolves the iron producing ferrous chloride. Oxygen in solution reacts with some of that producing ferric chloride. Once Fe(II), Fe(III), and CN- are all present Prussian Blue forms and precipitates out in fine particles. This is allowed to settle, the liquid is decanted, and the solid is rinsed with water. This process is repeated several times until all of the ferric chloride solution has been removed.

I've heard some people in Ohio are able to source vinyl chloride from their backyard lately, some can even bathe in it in their local stream.

Cool but I would not mess with HCN gas. Nice tip about the gum guar adding it to Prussian blue.

Prussian blue makes one of my favorite hues.

Jesus, the color was instant when you poured in the HCl. Cool!

Please make a special vid about HCN, I want to see it in its liquid form boiling close above rt 🫣😄

[TheStonerKoala]

Yes!! Welcome back PMC!!
The chemical King of YouTube is back!!! Spread the word to all corners of the flat Earth, fellow crazy internet people..

(Hopefully no fans of this channel seriously believe the flat Earth stuff 😂)

Again, welcome back, hopefully with Susan out of the picture some of the restrictive policies will also be gone.
Not gonna bet on it tho.
Cheers m8 🥂

I am so glad I used too do the whole hold breath under water for as long as I can thing as a kid in the swimming pool, because it sure is useful when I am like "Oh no, deadly gas" and being able too stop breathing for a bit too get into a place with better air is probably a great skill for keeping me alive!

[amanitaocreata]

I want to repeat it in an erlenmeyer flask with a tube in the cap and a balloon to catch the HCN 😂

Bout time you posted another video m8. Lol. Thought you were on holiday or something. XD jkjk

[dracrichards]

It would be neat to see someone use homemade Prussian Blue in tattooing. Food for thought for a possible future chemistry episode. XD

Hold your breath and fume hoods are for losers 🤣
