在初中化学实验中，最常用的酸碱指示剂是石蕊试液或由其浸制而成的石蕊试纸。你知道是谁最早发现和使用石蕊做指示剂的吗？他是英国著名化学家波义耳。说起他发现用植物色素做酸碱指示剂，还有一段小故事呢。lod年的一天，波义耳和他的助手在实验室内忙碌着：他们把盐酸从瓶内
In the junior high school chemistry experiment, the most commonly used acid-base indicator is a litmus test solution or a litmus test paper made therefrom. Do you know who first discovered and used litmus as an indicator? He is the famous British chemist Boyle. Speaking of his discovery of acid-base indicators using plant pigments, there is still a small story.
