Cromatografia na Prática! 🧪 Experimento com Caneta (ENEM na vida real)

Have you ever imagined discovering what pen ink is made of using Chemistry? 😳🖊️ In this practical lesson, Marcelão reproduces a simple paper chromatography experiment, inspired by ENEM questions, to show how this method of separating mixtures works. You will understand in practice: What chromatography is and how it separates mixtures; Difference between mobile phase and stationary phase; The role of capillarity in the process; How to identify the components of a mixture (pen pigments); Why some substances "rise" more than others; The concept of affinity/interaction with the phases; What elution and eluent are; How the polarity of solvents influences the result. 🔬 A simple, inexpensive experiment, perfect for understanding one of the most frequently tested topics on the ENEM! 🧠 Timeline: Experiment Proposal Materials Used (filter paper and alcohol) Chromatography Setup Capillarity and Beginning of the Process Result After the chromatographic Run Analysis of Pigments (green → blue + yellow) Affinity with Mobile and Stationary Phases Example with Black Ink Influence of Mobile Phase Polarity Elution and Eluent 💡 Support the Channel!
