Copper sulfate is an electrolyte.

Bile sulfuric acid is a natural hydrated copper sulfate(CuSO4·5H2O). It is the general name of this (CuSO 3·5H 2 O). In order to distinguish it from “anhydrous copper sulfate”, it is usually called “copper sulfate pentahydrate” with a relative molecular mass of 250, they widely exist in sulfate minerals.

The crystals of alum are plate-like or short-column-like. When these crystals are gathered together, they are granular, massive, fibrous, stalactite and crust-like. They have a beautiful blue color, but if exposed to dry air, they lose moisture and become an opaque light green white powder. At the same time, bile alum is very soluble in water

It can be used in agriculture, generally to prevent fungi and the like, as a fertilizer or fungicide. Regarding its use, the good aspect is that it can be sterilized, but if copper sulfate is used frequently, it may also affect the soil. Generally speaking, copper sulfate powder (CuSO4·5H2O)contains copper, which can provide essential copper elements for the growth of plants.

It can be used in animal feed because the copper in copper sulfate pentahydrate can help animals grow and reduce diseases, because both humans and animals require a small amount of copper in the body to promote metabolism and bone development. At the same time, it can help sterilize the gastrointestinal tract, which is similar to antibiotics. However, it is still necessary to control its use, because it can help animals reduce disease and is equivalent to growth hormone.

This(CuSO4·5H2O) is an important chemical product, which is widely used in the feed industry. There are also various methods for the preparation of copper sulfate pentahydrate. One of them is because copper cannot be directly dissolved in dilute sulfuric acid, so copper should be mixed Roasting and oxidizing, and then leaching with dilute sulfuric acid, this is a more traditional way of saying, and it is more time-consuming and costly.

There is another method, which is the air bubbling method, which is to blow hot dilute in the air. Sulfuric acid can be directly oxidized and leached. This method is relatively simple and saves steps and money. So this is the catalytic oxidation preparation of copper sulfate.

Sodium can replace the copper in copper sulfate(CuSO4·5H2O). You can remove a small amount of copper sulfate pentahydrate crystals, then place it in a container and heat it until the blue crystal becomes white copper sulfate, and then stop heating.

Take another small piece of sodium, absorb the kerosene on the surface of the sodium with filter paper, and put it into the container, then cover the white copper sulfate, and heat the container with alcohol until the metal sodium is melted. Stop heating.

Sodium and copper sulfate will react. After the reaction is over, add water to the container. After partial dissolution, pour out the solution. You can see the red solid in the container. Add a small amount of concentrated sulfuric acid solution and heat the red solid to melt and blue The solution, and has a pungent odor, indicating that the red solid is copper.

Therefore, sodium can replace copper in copper sulfate pentahydrate(CuSO4·5H2O).

The precautions for the prevention and treatment of fish diseases with copper sulfate(CuSO4·5H2O) are as follows:

1. Because the temperature of water is different in each place, copper sulfate pentahydrate has different antibacterial ability due to the temperature of the water, so when using it, pay attention to the water environment and the dosage.
2. Because the safe concentration range is relatively small, when using it, pay attention to measuring the volume of water and pay attention to its dosage.
3. Don’t use excessive kilowatts, because excessive use will affect the organisms in the water and may cause fish death in serious cases.
4. When in use, the temperature should not exceed 60C. If it exceeds 60C, it may cause failure and easily cause a large number of fish deaths.

It is commonly referred to as blue alum, bile alum, or copper alum. It is irregular block crystal, dark blue or light blue, translucent, like glass luster. Those that are larger, dark blue, transparent, and free of impurities are better. After ingesting this blue sail crystal, humans and animals will be poisoned, and in severe cases will be fatal. However, everything has two aspects. It is also toxic. It is also a common ingredient in herbicides and pesticides.

First of all, it is composed of copper and water. Copper is a necessary nutrient for rice growth. However, for rice, copper affects it indirectly, because it participates in the photosynthesis of rice. Function and respiration.

However, too much or too little copper ions will affect rice, among which, If the copper content is too high, it will also affect the growth of rice, making it impossible for plants to grow normally. However, if the amount is small, the lack of copper ions will lead to short growth, no growth, or even death. Therefore, it is necessary in the growth of rice.
