The iconic iodine test for starch has been a staple of biology and chemistry labs for over two centuries, first documented in 1814. This qualitative experiment reveals the presence of starch through a dramatic color change, a phenomenon rooted in the complex molecular structure of carbohydrates.

The iodine-starch test, a staple of chemistry and biology labs, has been used to detect starch since its discovery in 1814. This profound color change reveals the presence of starch and offers a glimpse into the molecular structure of this important plant carbohydrate.
