🧠 on Instagram: "The iodine clock reaction, discovered by Hans Heinrich Landolt in 1886, is a classic experiment that vividly demonstrates chemical kinetics. It involves a sudden color change from colorless to blue, illustrating the concept of reaction rates. This reaction occurs when two clear solutions are mixed, with one stage of the reaction taking longer, leading to a delayed color change. Widely used in classrooms, the iodine clock reaction offers a hands-on way to explore the factors inf

Dr. Pete Sulack on Instagram: "⚠️Most disposable plates contain PFAS (per- and polyfluoroalkyl substances)—chemicals used for water and grease resistance. But research shows: • PFAS disrupt hormone function and suppress the immune system → Grandjean et al., Environmental Health Perspectives, 2013 • Heating plastic or coated paper increases chemical leaching → Rudel et al., Environmental Health Perspectives, 2011 • Even small amounts of daily exposure can accumulate and interfere with detoxificat
