中学化学所使用的溶液中,有部份易变质不稳定的溶液需要临时配制。若长期放置这些溶液不仅会影响实验效果,而且还会发生燃烧
Among the solutions used in middle school chemistry, some of the unstable and unstable solutions require temporary preparation. If these solutions are left for a long time, they will not only affect the experimental results, but also cause burning.
