technostronomy on Instagram: "The iodine clock experiment is a classic chemistry demonstration that shows how the rate of a chemical reaction can be controlled and observed. It's called a "clock" because after mixing a few clear solutions, there's a predictable amount of time before the mixture suddenly and dramatically changes to a dark blue or black color.
