第一就是颜色(Colour change). Redox titration 具有一定的特殊性,由于在整个titration中 ions的种类发生了变化,即 ions oxidation number发生了变化,那么对于同一种element的不同ions,他们的颜色是不同的。也就是说,在大多数情况下,Redox titration是不用 indicator的,因为考reaction中ions 自身的颜色变化就可以来判...
在上一篇的文章中,CA带着大家回顾了titration比较重要的知识点,细心的同学们已经发现了,上篇文章的侧重点是acid-base titration, 那么在整个A-level中,对于titration这个实验,比较难的其实是redox titration。作为一向严谨的CA,对于这部分比较难的知识是一定...
Titration在考试中我们最常见的就是acid-basetitration,关于这个实验,我们需要清楚的知识点有以下几个:第一就是这个实验要用到的apparatus, 分别是 pipette, burette, conical flask. 在这里同学们要注意,带有读数/刻度的是burette, 如果考试中给你一个表格,那么它上面的result是从burette上得到的。第二个需要同学们...
