In Alevels chemistry laboratory class, we made Tollen's reagent and produced the silver mirror. The teacher allowed us to take the test tube home so I took the one my group made. I still have it with me.
My teacher told us to bring in a bottle that could close, because we were told to shake our reactions. I used a green wine bottle and it's gorgeous. We all took ours home as souvenirs. Same with our crystals.
Fred Singateh mustard gas is a combination of ammonia and chlorine sulfur might be added to it to make it fume more. those two when mixed evaporate the fumes of the solution are insanely toxic
borttor MCPE according to the big boy IUPAC, Mixing ammonia NH3 with bleach NaClO will create a small amount of chlorine gas Cl2 as well as several other biproducts such as N2 and more toxic products like hydrazine, chloromine, dichloromine and nitrogen trichloride. But not mustard gas. Because there is no nitrogen contained in mustard gas according to IUPAC. it is still very dangerous, but nothing but a myth you hear when people say it will create mustard gas. I would like to know where u heard tho so please respond.
I’m gonna be completely honest here; I’m a freshman. I don’t even *take* chemistry yet and 99% of the time when I watch these videos I am completely lost when it comes to chemical compositions and all that. I still watch these, though, all the way to the end, because there’s something oddly fascinating about watching all this be made even though I totally don’t understand why or how it works (I’m not saying you explain bad btw, I’m sure if I really paid attention to it I could understand just fine, I’m just very dumb and very lazy.)
Im not in college ,I am a welder . I have to watch a video sometimes a dozen times and work on and off for a week or 2 to half way to understand it .; But I will say Nile red is the easiest to understand and research
This was a year ago, so if you haven't taken chemistry yet, you'll learn nearly all of this stuff, them come back and you'll have a pretty good understanding of it
@@Landogarner83 That's right. My wife and i have some silver glass bell ornaments hat are about 125 years old at this point. They were made like this. They are still as bright as when made.
We had a task in a class test in school that was like "It's Christmas and all you realize you don't have any ornaments for your tree, so you decide to make some yourself" with this experiment. 😂 So, yeah.
I did this project in high school chemistry. I used a green wine bottle and it made a gorgeous green-gold mirror. After I saw how spectacular it was, I really wanted to try it on a red bottle. I saw someone who used blue, and it was pretty cool, but red... RED!
So, if a hungover cigarette smoker gets a bloody nose into Tollen's reagent will it create a silver mirror due to acetaldehyde in the blood? To my understanding smokers have higher acetaldehyde levels in the blood and the breakdown of alcohol in the human body creates acetaldehyde.
I'm guessing the effect of all the other aldehydes in the blood (glucose, amino acid residues) would be much larger than the effect of the acetaldehyde. So if it would work it would probably work with anyone's blood. But I suspect the insoluble cellular material would interfere with the aggregation of the silver into a mirror.
I did this in AP Chem back in High School. We lined the insides of old glass coke bottles.We made these right before Christmas Break, my chemistry teacher was the best.
When attempting this process, it's important not to accidentally make a silver colloid. Colloidal silver is not dangerous per se but its presence can be sensed by nearby flocks of suburban moms, who will attempt to take it to give to their young.
2:10 - The first time I knew something in a NileRed video without it being explained to me gets prefaced with "This sounds a little bit complicated..."
The fact these videos don’t make me mindless but there’s also the most interesting thing to watch in a time where I can’t leave my room because of covid makes me both sad and happy
I think the cloudiness you see on adding Silver Nitrate to water is actually Silver Chloride and other Silver salts precipitation out due to double displacement. With the exception of Nitrates, most silver salts have pretty low solubility in water. This would happen if the water you used has any contaminants.
I remember coating the insides of little test tubes this way in high school! It was part of our Christmas lab series. Super fun lab, it’s fun to see it again :-) (and in a lot more depth)
Fun fact: Silver nitrate, ammonia, and sodium hydroxide can also react to form the INCREDIBLY unstable and dangerous high explosive fulminating silver or silver nitride. You can see the properties of this chemical on Explosions and Fire’s video on “fulminating gold”
Just so you know, silver nitrate is often used in chloride tests. I've used it for years in my last job and that cloudy white color as you're trying to dissolve the solution is exactly what a positive indication looks like. TL:DR; if your silver nitrate isn't pure and is contaminated with chlorine (say from sea water), then the silver will combine with it to form silver chloride and that is most likely what you're seeing there.
I have a chemistry presentation on redox reactions. I will do the silver mirror to demonstrate an exemple of redox reaction and your video helped me a lot to write the equations and to determine a protocol, thank you. I hope I will be allowed to bring the silver flask home !
Changing of colours while mixing different chemicals by shaking the flask....is really fascinating for those who haven't even done a single experiment till now....🙂 And I'm one of them....😔
Are there any other mirror reactions that plate out different metals, like tin, copper, aluminium, iron, etc? It would be cool to see any that exist. Great video, cheers.
In our school in organic chemistry we make Tollen's reagens a little bit different. In a test tube we add about 1 mL of AgNO3(aq) then we add a drop of NaOH(aq) to for a dark brown precipitate and then we add as much aqueous ammonia as needed to dissolve previously formed precipitate.
this is why good education is important, everyone watching can think of millions uses and products that can be made from that reaction. imagine that you already knew that reaction, you could have already been busy making and selling Christmas tree bulbs instead of being the one buying them.
This!! This wowed me when our teacher showed it to us!! I think its one of the best methods to get children to like chemistry, especially organic! This and luminol :D
Speaking of that face reveal video, could/will the element series ever be a regular series that eventually gets through the elements you can get your hands on or will it just be when you happen to get some interesting elements?
NileRed: "For over a year I've endured harassment by a neighbor who objected to my smelly, dangerous chemical experiments. More than once she sicced the cops on me. So yesterday I decided to settle our differences by sending her a banana cream pie -- her favorite. Today I'll be conducting a 'Marsh test' for the presence of arsenic in her remains."
Whoa throwback. My chemistry teacher did a demonstration of this and told us it was used in the past to see if a person was suffering from diabetes. Really circumvented doctors tasting the patients' urine to check if it was sweet. Shame I didn't get to keep the test tube with the mirror. Someone else got it.
I would bet that the reason the stopper didn't get coated is that it didn't have an energy differential between liquid and air like the beaker did. It would be interesting to see how the reaction goes in a partially decompressed nitrogen controlled chamber.
How many years' bad luck is it to dissolve a mirror? 🤣 Thanks for these amazing videos. I never took Chem in high school or college, which I deeply regret. This stuff is amazing.
I remember many years ago I made a similar silver bottle but I definitely did not use glucose or ammonium nitrate. It was a very simple process. I recall a blue fluid I used, most likely silver nitrate. Wish I knew what I did, any video you see on youtube uses similar a method as yours.
You’re like the paragon example of why I’m taking chemistry in college. I want to be able to have such an extensive knowledge and able to put what I learned into use.
You can buy silver nitrate qtips used for medical purposes to fuse skin or for a procedure like ingrown toenail operations where they kill the nail root.
That is how they use to make old Christmas ornaments. Which is why the old glass and silver christmas ornaments are so collectable. This is also why breaking a mirror was bad luck, they were so expensive to make both the smooth glass and the silver coating and the whole process just to get the silver on it. The "bad luck" would deter people from breaking them more than "its expensive".
