摘要
本文对三草酸合铁(Ⅲ)酸钾的制备实验进行了优化,通过改变剩余H2O2去除时间、酸溶温度、结晶方式得到了结晶粒度较大、晶型均匀、色泽鲜艳的翠绿色菱形晶体,并且产品的产率可达65%。这一实验的改进,有助于激发学生实验兴趣,增进学生实验能力。
The experiment conditions were optimized for the preparation of potassium ferrioxalate. The big emerald crystal was obtained、yield was up to 65% by improving time of elimination H2O2、the temperature of adding H2C2O4、the manner of crystallization.
