What exactly is caffeine? Can you see it? Can you have a bowl of caffeine? How are some drinks decaffeinated?
In: Chemistry
Caffeine is a chemical naturally occurring in coffee, tea, chocolate, and some other foods. It’s a stimulant that works by blocking the neurotransmitters that make you feel tired.
Yes, you can see it if you get enough of it together. Like many pure chemicals, it takes the form of a white powder, but you can also buy it in pill form.
If you ate a bowl of caffeine powder you would almost certainly overdose and die.
Coffee is decaffeinated by “rinsing” it with chemical solvents that bind to caffeine. Caffeine-free teas are usually just herbal infusions that don’t naturally contain caffeine.
