Resumen:
picture is worth a thousand words,” and besides it is easier to remember. Thiswork is based on that
premise, and its main objective is to show that creating a strong visual impact on the student’s mind is a useful
tool to teach important chemistry concepts. The activities proposed involve a biphasic medium composed of an
aqueous solution at different pH levels and petroleum ether (60–80C), where an acid-basic indicator such as
methyl red is employed to examine the phenomenon occurring in each phase, as it changes its color like a
“chameleon.” During the process, students are introducedto core concepts of physical chemistry through a
solvent partition system. The experiment is suitable for both qualitative and quantitative analyses of the
extraction process
