硫酸铜是一种常见化学试剂，它常以白色粉末状无水硫酸铜和蓝色晶体水合硫酸铜存在。它作为化学试剂在中学化学中有着显著的位置。初中化学中最初认识化学变化和物理变化时，有水合硫酸铜的失水实验，蓝色晶体加热变成白色粉末。通过这一实验，学生初步了解到化学变化的特... Copper sulphate is a common chemical reagent. It is often present as white powdered anhydrous copper sulfate and blue crystalline hydrated copper sulfate. It has a prominent position as a chemical reagent in middle school chemistry. When chemical and physical changes were first recognized in junior high school chemistry, there was a dehydration experiment of hydrated copper sulfate, and the blue crystals became white powder by heating. Through this experiment, students initially learned about the special characteristics of chemical change...
