CuSO4 5h2o, the chemical molecular formula of gallstones is CuSO4 5h2o, also known as copper sulfate pentahydrate. With a relative molecular weight of 250, vitriol can combine with protein to form insoluble protein compound and precipitate, so its concentrated solution has corrosive effect on local mucosa, while its dilute solution has astringent and secretory effects.
Copper sulfate pentahydrate is a pure substance, commonly known as sulfuric acid. It is copper sulfate of pentahydrate, which is a blue crystal at room temperature. Copper sulfate solution is a blue solution formed by dissolving copper sulfate in water. Pure copper sulfate without crystal water is white powder.
We can drop water on copper sulfate to get copper sulfate pentahydrate. Crystal structure CuSO4 5H2O crystal structure, Cu ion is octahedral coordination, surrounded by four H2O and two O, and the fifth H2O is tetrahedral with two H2O in Cu2+ octahedron and two O in SO42-, which plays a buffering role in the structure.
physicochemical properties
The physical properties of copper sulfate are blue transparent crystals. Soluble in water, slightly soluble in dilute ethanol, insoluble in anhydrous ethanol. The chemical property of copper sulfate is that it can easily absorb water vapor in the air and become hydrate.
It reacts with simple materials whose activity sequence is before copper, such as iron, zinc, etc., but it cannot be replaced by excessively active metals. React with alkali. It reacts with ammonia water to produce a small amount of copper hydroxide, and when it is excessive, it produces a complex of tetramine copper sulfate.
Knowledge expansion
To learn chemistry well, here are some suggestions:
Cultivate interest in chemistry: chemistry is an interesting subject, and understanding and cultivating interest in chemistry is the first step to learn chemistry well. You can cultivate your interest by reading chemistry-related books and paying attention to chemistry news and experiments.
Master basic knowledge: The key to learning chemistry well is to master basic knowledge. To start learning chemistry, we should start with the basic knowledge, including the periodic table of elements, atomic structure, chemical bonds and so on. It is suggested that you take notes during the study to facilitate review and review.
Integrating theory with practice: Chemistry is an experimental science, and practice is an important means to learn chemistry well. Taking part in experimental courses or projects while studying chemistry is helpful to consolidate and understand theoretical knowledge. At the same time, we should abide by the safety rules and pay attention to the accuracy and meticulousness of the experimental operation.
Consolidate knowledge by doing problems: chemistry is a subject that needs to be understood and applied, and knowledge can be consolidated by solving problems. You can find related problem sets and practice according to different chapters to strengthen your understanding and memory of knowledge points.
Participate in discussions and exchanges: participating in discussions and exchanges can broaden the understanding of chemistry. You can participate in extracurricular activities related to chemistry, attend academic seminars or join academic societies. And share your learning experience and opinions with others.
Resource utilization: There are many chemistry learning resources available now, such as chemistry textbooks, online open classes, academic papers and scientific research documents. Make full use of these resources to expand the understanding and learning of chemical knowledge.
Perseverance: Learning chemistry well requires persistent efforts. Chemistry is a subject that needs repeated training and mastery. We should persist in studying, be diligent in practice, and constantly improve our understanding and ability.
In short, learning chemistry well requires interest, basic knowledge, practical experience, problem-solving ability and continuous efforts. I believe that as long as you pay enough time and energy, you can understand and master chemistry knowledge and become an excellent chemistry learner.
