Crimson Romance

School of Chemistry and Materials Science, Guizhou Normal University, Guiyang 550025, China

Received Date: 12 November 2023
Revised Date: 4 February 2024

Behind some romantic and magical illusions lie chemical reactions. This experiment revolves around captivating phenomena related to "crimson romance," engaging the public with a few simple and intriguing demonstrations of chemical reactions. Among these, the complexation reaction between potassium thiocyanate and iron ions produces a blood-red flocculent complex, which promptly disappears when it reacts with sodium fluoride. Additionally, the iron in hemoglobin can generate blue fluorescence when paired with luminol. By showcasing these enchanting and romantic phenomena, this study aims to disseminate chemical knowledge across various demographics, unveiling the secrets behind magical illusions and delving into the beauty of chemistry. This approach encourages individuals to adopt a scientific perspective, fostering admiration for chemistry and showcasing its inherent magic and allure, thereby igniting curiosity and passion for chemistry among students and the general public.
- Blood color,
- Potassium thiocyanate,
- Luminol,
- Complexation reaction,
- Science popularization across diverse demographics
