相信大家愿意讨论这些问题,因为这是我们中学化学教学中教师很难回避的实际问题。1.因存放不当KI在空气中会氧化变质泛橙黄色(不像单质I_2,倒像Br_2水),相同情况下白色的KI淀粉试纸为什么相当稳定不变色呢?
I believe we are willing to discuss these issues because this is a practical problem that teachers in high school chemistry teaching find it difficult to avoid. 1. Due to improper storage KI oxidative deterioration in the air pan-orange (unlike the element I_2, like Br_2 water), under the same circumstances why the white KI starch test paper is quite stable does not change color?
