WARNING: This is very specific for getting acid on hands. Skin elsewhere on the body is much thinner, and will be damaged much much faster.
Note: I will eventually re-do this video. I missed a lot of important information!
Hello everyone. First of all, I apologize for the poor video angle in this.
PLEASE DO NOT REPEAT THIS.
In this video, I will be pouring three common acids on my skin. I'll pour hydrochloric acid, nitric acid and sulfuric acid. This is only true for room temperature acids. Hot acids are a different story. The 300C sulfuric acid in my distillation video will instantly char your skin. ... https://www.youtube.com/watch?v=XeVZQoJ5FdE
Today we are extracting citric acid from some large large lemons. Citric acid is quite a useful molecule in general, but I don't have any particular uses for it. It is mostly used as a pH buffering agent in chemistry and isn't use in direct synthesis.
A buffering solution is a solution that resists pH change. It is useful in synthesis when you need to keep the pH relatively constant during a reaction.
In my Cadaverine video, I used citric acid to make a pH buffer solution: https://youtu.be/C5hxFAwKIzs

Today we will be doing a demonstration of the Tollen's test and the silver mirror.
The Tollen's test is mainly used to identify aldehyde groups (forms a silver mirror) and it was historically used a lot. It was slowly replaced with more accurate and better techniques. However, it is still very useful for hobbyist who can't afford big expensive machines.
The silver mirror is kind of an off-shoot of the Tollen test, where all we are after is the mirror that forms. We use glucose because it is a cheap and easy aldehyde source.
In the future, I might make a video where I identify an uknown chemical using a series of classic techniques.

Today, I'll be revisiting something that I did 4 years ago, as one of the first videos for the channel!

We will be extracting some caffeine from coffee today! I used regular coffee grounds, but I think the process is actually faster and easier with instant coffee.
In theory the yield should have been hovering around 300mg if ALL the caffeine was removed. However, I got around 10% of that (30mg). Apparently 10g makes about a cup of coffee, so a yield of 30mg isn't that horrible.
Industrially, the caffeine is made synthetically and not extracted because it isn't really economical. The only time caffeine is extracted is for making decaffeinated coffee. But in that case, the end product is the coffee itself and the caffeine is a by-product. It is just much cheaper to make the caffeine directly.
Ill be doing a future video on how to get caffeine from caffeine pills.

Sorry for the slow videos, I am very busy lately. Summer is coming though, so I can make some bromine and other fun stuff! :)

TO THOSE WHO ARE CONCERNED. THIS IS THE LAST PIRANHA VIDEO FOR A WHILE!! THIS CHANNEL IS NOT BECOMING A PIRANHA CHANNEL
Also, Patreons are not charges for any of the non full length and in depth chemistry videos.
This video was just sitting around doing nothing, so I figured I would post it in celebration of hitting 50k subs. I do want to do a real and proper 50k celebration video, so that will be uploaded eventually.
When we soak the chicken in acid, the most interesting part is that the chicken turns white and appears cooked. The strong acid has a similar effect as heat which denatures the proteins that give the chicken its reddish color.

In this video, I'll be talking about the very interesting element Mercury. I try to cover as much as I can, including its properties, its history and interesting reactions.
Let me know what other element you would like to see. Keep in mind that this takes a lot of work though, and that not all elements will be possible (due to rarity and/or danger).
Let me know if I forgot anything in the description. I probably left out links or something.

Today we will be making and playing with a little bit of liquid oxygen!
Be aware that this is dangerous. It is very important not to drop a liquid fuel into it. It could explode!

This is just a regular light bulb, but I'm only interested in its insides. This is because I've been curious to see what happens, if I turn it on in liquid nitrogen.
