Analyser un liquide ? Réfractométrie !

⚛️ How can you analyze a liquid by measuring its refractive index? Let's take a look at this using a widely used device available in laboratories and high schools: the refractometer. ✅ ORGANIZATION OF THE VIDEO: 👉 0:00: Introduction 👉 0:40: Background: Refractive Index 👉 1:30: Abbe Refractometer 👉 1:45: Measurement Protocol 👉 4:20: Influence of Temperature 👉 4:35: Cleaning 👉 4:55: Interpretation of the Result 👉 7:45: Analysis of a Deteriorated Sample 👉 8:30: Intermediate Conclusion 👉 9:15: Further Reading: Measurement Principle 👉 12:10: Wavelength 👉 12:34: Conclusion ✅ To check your understanding, take this quiz: 👉 https://forms.gle/GBezSw6DfA61YaYR7 ✅ VIDEOS related to the topic: 👉 Recrystallization:    • La recristallisation   👉 Column Chromatography:    • Chromatographie sur colonne   👉 Thin Layer Chromatography:    • Chromatographie sur couche mince (CCM)   ---------------------------------------------- 💻 FIND BLABLAREAU ✅ Website: https://blablareau-chimie.fr/ ✅ Social Media: 👉 Instagram: blablareau_au_labo 👉 Facebook:   / blablareauaulabo   👉 Twitter: @Blablareau ✅ SUPPORT video creation: 👉 Tipeee: https://en.tipeee.com/blablareau-au-labo 👉 U-tip: https://www.utip.io/feed/blablareauau... ✅ Secondary channel for higher education students:    / @blablareauautableau   ---------------------------------------------- 💻 FIND MEDIACHIMIE 👉 YouTube channel: https://www.youtube.com/user/mediachi... 👉 Website: https://www.mediachimie.org/ ——————————————————— 🙏 ACKNOWLEDGMENTS ✍️ Video co-written with Françoise Brénon 🧮 Refractometer diagrams: @prof_Mejean (on Twitter, YouTube, and Instagram) 👉    / profomejean   🎶 Music: Delay Lama & Fabrice Blareau 👉    / @zionco6726   ✊ Kung Fu Technique with Jean-Baptiste Leroy
