In this video, we dissolve some silver ingots in nitric acid to make silver nitrate. I plan to use silver nitrate in a few ways. I want to revisit the water sensitive mixture of magnesium and silver nitrate and I want to make the silver mirror (which I have surprisingly never done).

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.
