Students, teachers, hobby chemists, and chemistry enthusiasts alike can enjoy the detailed workings of many different and often common chemical laboratory preparations, narrated and explained for clarity and education.
I'm confused. He says he's running a 4 molar scale reaction which I guess would normally include 4 moles of water, (which is 72.06ml), though his mollecular notation diagram didn't include water, and at 2:17, he says he adds "nearly 9 extra moles of water" to the reaction side to facilitate carrying the nitric over. That's 162.13ml (Is that 9 on top of the presumed original 4, or just 9 total?) All well and good right, but then at 4:30 says he's adding 200ml of water to the reaction side.. 200ml is 11.1 moles of water, not 9 moles. And if you include the roughly 7% water in the 232ml of 93% h2so4 then that brings the total water volume in solute to about 216.24ml which is 12.003 moles of h²o. So, does it matter how much water you add? It doesn't seem like it does. I guess your end distillate would just be more dilute right? But why did he say he adds 9 extra moles of water and then proceed to add 11 moles? How come nobody else has pointed this out or asked about it? Is there an ideal amount of water to add to this reaction?
Great video. Informative and educational. Along with NurdRage's video, I was able to make dioxane on first try withourt messing up. But, Doug, my man, you talk way too fast and should fine tune your presentation, polish it up. Still, I rank it right up there witrh NurdRage. And that is a compliment.
Hello, my teacher, don't be tired. Is there carbon tetrachloride or chloroform in this methylene chloride that you made? Or is there only methylene chloride?
Can I use anhydrous sodium hypochlorite? Ive got so much of it, as i found a huge bucket at a construction site (take it easy it was outside of the site and i only liberated 8 lbs of it!) But I didnt realize that it was way too much for me as I will never use all of it. Plus im hearing anhydrous sodium hypochlorite is Explosive? Any feedback will surely be appreciated. Take care
So I've distilled h2so4 3 times now following your setup, minus the leibig condenser and substituting a Vigreux column. I also purchased a small terracotta plant base, broke it into small chips, ground the sharp edges and used them as boiling chips. Each time I've don't this I've ended up with quite a bit of white powder in my leftover discard solute. I speculate this is silica from the portion of terracotta that has dissolved, but I'm not sure, any ideas?
Very Toxic. 😂😂😂I worked in a factory full of Mercury. And it was full of it and no one died or get seek of mercury. Who made it toxic??😅😅😂😂 We have it in our tooth
