近年提出的微量化实验改进了微型实验的不足,以微小量试剂在较常规的仪器装置中进行化学实验,使实验现象依然足够明显,在保证了试剂用量少、污染小、省时、易操作的同时,仍能达到常规演示实验的可见度。因此,在中学化学实验中研究 In recent years, the micro-quantitative experiments to improve the lack of micro-experiments, with a small amount of reagent in the more conventional instrument in chemical experiments, the experimental phenomenon is still significant enough to ensure that the reagents used less pollution, time-saving and easy While operating, the visibility of routine demonstration experiments can still be achieved. Therefore, in high school chemistry experiments
