I refine some more silver using homemade nitric acid. Ok so maybe a little longer on that 250K video.. Help me make videos by donating here: / codyslab
+Grant Thompson - "The King of Random" It is some what of a running gag that I am trying to work into my videos, the rabbit will always be a different color and will be increasingly hard to find in the background. Might be a dumb idea but it sure gives people something to comment on.
Cody'sLab is it so real rabbit or did you chemically make it? It's easy to make rabbits ya know, you need Rab² and Bit⁴ to make a rabbit. Stay away from ha¹³ and re²¹ they make feisty lil things.
I really don't know of that many Utah based RU-vidrs. Thanks for posting these videos! I have almost no idea what's going on, but you still manage to make these entertaining enough for someone who doesn't know the difference between acids or even what a "Base" is. Hopefully as I watch more and more I will learn these things!
Cody: You Rock! I LOVE your videos and often find myself referring to your videos in my hunt to find gold. Than you for sharing your knowledge and insight. They've been an essential part of my prospecting ventures. Hopefully I'll be able to find enough gold to get me on my feet and reunite me with my beloved son. When I do, I'll post a video of us thanking you for your help! Sincerest gratitude. Carol n Timothy
@@theCodyReeder I wrote that comment 8 years ago and now you've got 2.16 MILLION subs !! On the off chance you see this reply, no need to respond, just wanted to say a huge THANK YOU for all the shared knowledge and adventures you've taken us on so far, you truly have made the world a better place.
You should make more videos on taking resources from the land and refining or using them to create things. It's very fascinating. I love your channel, keep up the good work!
Amazing how quickly everything "springs back to life" after being one of the south west's coldest snaps in some time.. Time flies I suppose being the beginning of May. Nice Fiji water bottles by the way. Onward to 1 M subs. Mmm perhaps sir as the Fiji bottles give way to Grey Poupon bottles the ultimate in water vessels, the fine cut Crystal bottle maybe pouring the water soon? Just kidding and congrats on the major win here. Props are well deserved with someone so smart and well rounded. Excellent channel, sounds and video.
Man I'm always hyped when I see a Cody video in my subbox... I don't understand anything about the science in those videos but it's still so satisfying to watch *-*
How about extracting lead from crystal glassware. Was always curious on how much lead is actually used in crystal glassware and the different percentages of lead in the crystal as well.
Hi Cody, I never took chemistry in school but if I had you for a teacher I most definitely would have. You make everything fun and exciting to watch your experiments. Take care, Paul
your hopes are dead, because he isn't doing this kind of videos anymore, it was funny , but now, the channel is dead and he just keep posting videos because he don't want to lose his 9 year work and deceive people. I'm just watching his old videos to remember how he was great.
love the retort!! first and only video I found where someone uses a retort. I have a huge 8liter pyrex retort from the 1940s I want to use some day in my lab.
Cody's introduction always reminds me of myth busters and it made me think, Cody could have been a myth buster!! Him, Adam, and Jamie would have been unstoppable
+Ron Hombre RU-vid is pretty slow with these things. If I recall, there have been some youtubers who get the next play button up BEFORE they got the silver one.
The geology department at my university was throwing away a bunch of geological survey reports and maps from 1918 - 1960s, I grabbed them in case you'd be interested in them. I had sent you an email about the a while back, but I hadn't heard back so I didn't know if it got through. Thanks for making the great videos, I look forward to seeing them as they come out. Keep up the good work!
Right on man, hope you had fun. Seemed like a bit of an ordeal to get it all processed, but I'm glad you worked it all out. The next time I sweep a bunch of something valuable off the shop floor, I'll let you know!
i am planing to make some nitric acid like this once i find new source of KNO3 (which is impossible last 2-3 years here :( ) so i want to ask is there any easy way to remove the NO2 from the result? is it enough to let it sit on open air for some time?
***** thanks for the suggestion, but here our gardening stores have only fertilizers and if I find KNO3 it will be as fertilizer (noone even knows about stump removers here), and i would need to even recognize it my self somehow because they dont even know what they are selling, its all fertilizer for the gardening store sellers here... they all sell NH4NO3 (nitrogen fertilizer as they are calling it) but noone sells KNO3...
+Jellyf0x The sulfuric acid azeotrope with water forms at 98.3% acid. This fumes quite badly in air though, so most commercially bought acid (including some types of drain cleaner sulfuric acid) come at concentrations between 91 and 95% acid. Sulfuric acid can in fact be brought above 98.3% concentration, but it cannot be done by distillation. Instead, sulfur trioxide gas is passed through the acid to strengthen-- this reacts with any remaning water to produce more sulfuric acid, and eventually it will react with sulfuric acid itself, forming oleum.
Oh my mistake, I thought you meant the sulfuric acid. For nitric acid, it does form an azeotrope with water at around 68% nitric acid, but there's so little water in the system that it simply can't distill off as the azeotrope-- there's nowhere for the water to come from. Also Cody, there's a much better way to produce concentrated nitric acid than using KNO3, if all you're looking for is ~70% concentration. Just use some cheap drain-cleaner grade sulfuric acid (titrate it or use a hydrometer to calculate its water concentration), dilute with a stoichiometric amount of water, and add calcium nitrate. This causes calcium sulfate to immediately precipitate below a much more water layer of acids, and the nitric acid can then be easily distilled off. This is a better method than the method with KNO3 as while the calcium nitrate route produces effectively innocuous calcium sulfate powder as a byproduct, potassium nitrate produces strongly acidic potassium bisulfate. This is much less environmentally friendly, and plus it's just a waste of perfectly good sulfuric acid. Also, the potassium bisulfate formed tends to cake -- this inhibits heat transfer throughout the flask and causes the nitrates to decompose to nitrogen oxides. The calcium nitrate method, when well-run, can produce water-clear azeotropic nitric acid.
+Mr Mürk Cmon...they lost a bit of the morrowind but oblivion and skyrim are still some of the best fantasy exploration games out there. If there's better I'd love a recommendation.
Everyone sees colour a little differently, green/blue is a fairly common form of colourblindness. It should look green to most folks, but a lot of folks will think it's a blue bunny.
Ghorda9 because during the day the angle at which sunlight passed through our atmosphere , blocks most wavelengths of light except for blue, thus the sky to humans looks blue, the sky can also vary in hue and colour dependent on time of day and atmospheric conditions such as humidity, sometimes resulting in a red or pink colour
Cody, why did you chose to add the water to the acid at 2:10, I've always been taught to add acid to water when diluting? I always figured this was for safety reasons, so do you just have to pour slowly?
It's not just due to splashing. Diluting concentrated acids produces a really large amount of heat as well which may cause the glass article to shatter due to rapid heating and cooling. When you add small amount of water to a large amount of acid, all of the acid starts creating heat due to dilution while if you do the reverse, the water dissipates the heat the acid creates thus making it overall safer.
One of the beauties, in my opinion, of chemistry is that it can be such a colorful science. I really hope all goes well with school so i can actually find a career pertaining to it
Cody... Can you just make a video on making Nitric Acid using your Retort.. I have a 1000ml Retort and not sure of the exact amount of Nitrat to Sulfuric Acid to mix.. Thank you !!!!
There is a video from Nile red showing how you can make nitric acid and the exact mix the video is "how to make fuming nitric acid" it's really good quality
+Dj Ruccy they don't belong in jail for choosing to take drugs and possibly hurt their body. Their body their choice.The arrogance of dictating what people can and cannot do even though it doesn't hurt anyone else is astounding.
It does not matter much. Both way would do the same exothermic reaction, making heat. The best way to think of this is : Pour the smallest of both into the largest of them. If you use more acid than water, then you add the water after and vice versa.
sry but ive never heard such bs. the drop acid you pour onto water is instantly diluted, and because of the high heat capacity of water it wont spill if done correctly. if you do it the other way around the water could get evaporated and spill hot conc. acid everywhere. so its really a preference what u like more on your skin, hot concentrated acid or diluted acid...
ChemistryMadness watch Cody's own videos about adding water to acid for proof against what you are claiming. He even stated that in this video or the previous one.
I worked in a gold/silver refinery over three decades ago but they turned silver coils, silverware extra into silver crystal then melted that down. They also cut up x-rays by the hundreds of tons then soaked them in a cyanide solution and ran that into a plating system.
