How to write the chemical formula of bile alum is as follows:

CuSO4-5H2O, the chemical formula of bile alum is CuSO4-5H2O, also known as copper sulfate pentahydrate. The relative molecular mass of alum is 250, can be combined with protein to produce insoluble protein compounds and precipitation, so its concentrated solution of local mucous membranes have a corrosive effect, dilute solution has astringent system of urinary effect.

Copper sulfate pentahydrate is a pure substance, commonly known as alum. Is with 5 water of crystallization of copper sulfate, blue crystals at room temperature. Copper sulfate solution for copper sulfate dissolved in water to form a solution, blue. And pure copper sulfate without water of crystallization is white powder.

We can get copper sulfate pentahydrate by adding water dropwise to copper sulfate. Crystal StructureThe crystal structure of CuSO4-5H2O shows the Cu ion in octahedral coordination, surrounded by four H2O and two o's. The Cu ion has an octahedral coordination. The fifth H2O is connected to the two H2Os in the Cu2+ octahedron and the two os in the SO42- in a tetrahedral shape, which plays a buffering role in the structure.

Physical and Chemical Properties

The physical properties of copper sulfate are blue transparent crystals. It is soluble in water, slightly soluble in dilute ethanol and insoluble in anhydrous ethanol. The chemical property of copper sulfate is very easy to absorb water vapor in the air and become hydrated.

Replacement reactions with monomers whose order of activity lies before that of copper, such as iron and zinc, but not with overly reactive metals. Reacts with bases. Reacts with ammonia to form copper hydroxide in small amounts and the complex tetraammine copper sulfate in excess.

Knowledge Expansion

To learn chemistry, here are some suggestions:

Cultivate an interest in chemistry: Chemistry is an interesting subject, and understanding and cultivating an interest in chemistry is the first step to learning it well. You can cultivate interest by reading books related to chemistry, following news and experiments on chemistry, etc.

Mastering the basics: The key to learning chemistry is mastering the basics. When you start learning chemistry, start with the basics, including the periodic table, atomic structure, chemical bonding and so on. It is recommended that you take notes during your studies to facilitate review and revision.

Theory combined with practice: chemistry is an experimental science, and practice is an important means of learning chemistry. Participating in laboratory courses or conducting experimental projects while studying chemistry will help consolidate and understand theoretical knowledge. At the same time, it is important to observe safety rules and pay attention to the accuracy and meticulousness of experimental operations when conducting experiments.

Doing problems to consolidate knowledge: chemistry is a subject that requires understanding and application, and knowledge can be consolidated by solving problems. You can find relevant problem sets and practice according to different chapters to strengthen your understanding and memory of the knowledge points.

Participating in discussions and exchanges: Participating in discussions and exchanges can broaden your understanding of chemistry. You can participate in chemistry-related extracurricular activities, attend academic seminars or join academic societies, etc., to communicate and share your learning experience and views on chemistry with others.

Utilizing resources: Nowadays, there are a lot of resources for chemistry learning that can be utilized, such as chemistry textbooks, online open courses, academic papers, scientific research literature and so on. Make full use of these resources to expand your knowledge and learning of chemistry.

Consistency: Learning chemistry requires consistent effort. Chemistry is a subject that requires repeated training and mastery, so it is important to persevere in your studies, practice diligently, and continue to improve your understanding and ability.

In short, learning chemistry well requires interest, basic knowledge, practical experience, problem solving ability and sustained effort. I believe that if you put in enough time and effort, you will be able to understand and master chemistry and become a good chemistry learner.
