一、背景在一些侦探小说和魔术中,时常会出现让人感到惊奇的隐形墨水。随着中学化学学科的学习,我们对隐形墨水的显色原理有了一些了解,因此在研究性学习倡导的“学科知识和兴趣爱好兼顾”的前提下,我们提出了本课题。二、目的及意义熟悉一些变色反应的原理和化学实验的操作,提 I. Background In some detective stories and magic, invisible inks often appear to be surprising. With the study of the chemistry discipline in middle school, we have some understanding of the principle of color development of invisible ink. Therefore, under the premise of research education’s advocate of “disciplinary knowledge and interest-loving considerations”, we have proposed this topic. Second, the purpose and significance Familiar with the principle of some color change reaction and the operation of chemical experiment
