摘要
在一些浪漫神奇的魔术背后都隐藏着化学反应.本实验围绕以大众感兴趣的,且与"血色浪漫"相关的神奇现象展开,以简单有趣的几个现象科普化学反应的魅力.其中由硫氰酸钾与铁离子发生络合反应生成血红色絮状络合物,其生成物与氟化钠反应后血红色便会立刻消失,而血红蛋白中的铁可与鲁米诺产生蓝色荧光.在展现这些神奇而浪漫的现象的同时向各个层次人群科普化学知识,解密神奇魔术,探索化学之美,让人们用科学的角度来看待事物,敬佩化学,也充分展示化学的神奇与魅力,有助于激发中小学生和社会大众对化学的探索兴趣与热爱.
Abstract
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.
