What is the stinging agent, related to water treatment, for example, MAS207 is an effective stinging

The stinging agent is an organic substance that can form a stable "chelate" with certain unstable divalent metal ions, such as iron, manganese, zinc, etc., to help these metal ions maintain a stable state in water and promote the absorption and utilization of aquatic plants.

In water, metal ions may be oxidized or precipitated by chemical reactions, which can affect the growth and growth of aquatic plants. The use of stinging agent can avoid this situation, so that the metal ions can maintain a stable state and can be effectively absorbed and utilized by aquatic plants.

For example, mas207 is an effective binding agent of iron and manganese, which can form stable chelates with metal ions such as iron and manganese, so that these metal ions can play an effective role in the breeding of aquatic plants.

Chelating agent, not sting.

Chelating agent is an organic substance, which can form stable "chelates" with some unstable divalent metal ions, such as iron, manganese, zinc, etc. It is easy to be oxidized in water or easy to be chemically reacted.

Precipitated aquatic weed fertilizers often need to be chelated to form stable chelates to facilitate the absorption and utilization of aquatic plants.

The most obvious example is that ferrous ions often need to be protected from oxidation or precipitation by chelating agents, and iron ions are known to be indispensable and important trace elements in the breeding of aquatic plants.

One. Therefore, chelating agents have become a worthy complex in fertilization control.

Its importance cannot be overlooked.

Actually, it's not that complicated, it's just some complexes.

Chemistry is a kind of natural science, which studies the composition, properties, structure and change laws of matter at the molecular and atomic levels. The science of creating new matter. The world is composed of matter, and chemistry is one of the main methods and means used by human beings to understand and transform the material world.

It is a discipline with a long history and vitality, and its achievements are an important symbol of social civilization.

Knowledge Extension] Science subjects are: Chinese, Mathematics, English, Physics, Chemistry, Biology Liberal Arts subjects are: Chinese, Mathematics, English, Politics, History, GeographyNote: Liberal Arts Mathematics and Science Mathematics are different, Science Mathematics is a little more difficult, Chinese and English are the same.

Chemistry belongs to the sciences, but because there is a lot of content to memorize, it is called "the liberal arts of science".

In middle school, it is science, and after university, it is divided into engineering or science, depending on the situation. In the process of learning, there will be things to memorize, which seems to be liberal arts, and if you understand it in place, you don't need to memorize it!

Science, of course! Liberal arts are geography, politics, history. The sciences are chemistry, biology, and physics.

Liberal arts in the sciences. If you don't understand, it's hard to learn.

In chemistry n stands for: n, the elemental symbol for nitrogen.

Macroscopically represents nitrogen; Microscopically represents a nitrogen atom. An element symbol is a unique symbol used to mark an element, and can also represent an atom of such an element, and most solid elements are also commonly represented by element symbols.

The amount of nitrogen in the earth's crust is very small, and the vast majority of nitrogen in nature is in the form of elemental molecular nitrogen in the atmosphere, which accounts for 78% of the volume of air. The most important mineral of nitrogen is nitrate.

In some engineering and physical chemistry books, I have seen the use of n to indicate the number of particles.

And even na, which is Avogadro's constant.

However, there are many examples of the number of particles, that is, the amount of matter multiplied by Avogadro's constant, and the number of molecules and atoms.

The amount of a substance, in moles.

The nitrogen element, which can also refer to nitrogen atoms.

The unit is mole and the symbol is n!!Do you understand? Flip the book.

It's still going to be good.

CopyGood lectures.

I'm also a chemistry major, a freshman.

When Du was a sophomore, he didn't study well and went to class

Don't listen to classes, and copy homework after class. Our organic chemistry teacher didn't speak very well...... eitherIn my junior year, I started to listen carefully to the lectures, and then at the end of the semester, I was able to score more than 90 points without revision. There are a lot of credits in my junior year, and I relied on my junior year grades to secure my graduate school.

You must work hard, if you are going to graduate school, you have to study again, study hard now, and save yourself from piling up together in the future.

Friends above, you come with me.

I think the same, but it is best to rely on my own understanding to have a self-esteem.

Of course, you have to rely on the back to know those.

DAO learns formulas and common sense, that's all, the most important point is to work hard to get good grades, I hope you can be admitted to the school you love.

I didn't get into my favorite school when I took the high school entrance examination, and now it's a pity that --!

Hehe, chemistry.

There's no way, you can't learn well if you don't memorize.

I only have one word for chemistry. Inner back. Chemistry is the liberal arts subject of science, and there are many things in chemistry that need to be memorized. Like what.

Valency, the electron shell of the element, the electronic structure, etc. As long as you can memorize some chemistry things well, I think your chemistry will make a qualitative leap. My chemistry was memorized in the exam, and I got 98 in chemistry and only got one multiple-choice question wrong.

I got more than 70 in the college entrance examination. It's all memorized.

Well, that's it for you. I think you'll have your own set of methods.

It is important to pay attention to revision, just read the book two or three times. University is different from middle school, don't die to do questions, pay attention to understanding and expansion, that is, read more relevant professional books.

Hard work plus sweat, plus diligence plus interest. Interest is the best teacher. Choosing a chemistry major is enough to see how much you love chemistry. Regain your self-confidence. There's a book called "Chemistry is Fun" that you can check out.

The scope of chemistry major in college copy is relatively wide, if you want to learn chemistry well, you must pay attention to the key points of Mr. Du's teaching, and if you don't understand the key points, ask Mr. Dao, and understand the content of the study, and do more exercises to consolidate the key knowledge points, so you must buy some reference books or borrow some professional reference books from the library to figure it out and figure it out.

I'm also a sophomore in chemistry, and I think college chemistry is pretty good. It's not difficult to be a member, is it that you haven't done enough work before and after class? If you know that you can't change your major, then study hard.

You also know that you can study well in college as long as you keep half of your high school seriousness.

I guess you haven't learned the basic knowledge part, the first half of inorganic chemistry is very important, you must understand it, so that the second half of inorganic chemistry is good-looking, organic is not difficult, and it's good to analyze and do more questions. That's all my opinion.

I'm also a chemistry student, and I feel the same way as you, but I don't like chemistry!

Now think about du, if you really don't like it.

Zhi Huan, let's develop in other aspects! dao

If you still want to further your studies, it is recommended that you consider the interdisciplinary examination and learn the major you are really interested in, I think you still have to do what you like, it is easy to achieve, so that you are not easy to get tired!

Hehe, the same disease, Bai pity.

Du I am also a sophomore, majoring in chemistry.

I can't understand it after class, so I rely on the final assault.

If you can't stand it the most, you will answer.

It's to do those dangerous experiments, I'm really afraid that one day I will be splashed with concentrated sulfuric acid.

I have decided not to go to graduate school because I know that I will not be able to pass the exam, and even if I do, I dare not imagine my future work.

Nowadays, there are a lot of people who don't have the right professional work, and you don't necessarily have to do this to learn this.

Although you can't change majors, you can have the motivation to be interested, maybe you will find a good job in the industry you like, and more importantly, you can find your heart.

I wish you to find your true heart soon.

Find a tutor who studies well.
