3. Main courses.

Advanced Analytical Chemistry", Advanced Instrumental Analysis, Modern Electroanalytical Chemistry, Microfluidic Chip Analysis, Introduction to Nanomaterials, Materials Characterization Methods, Modern Spectroscopic Analysis, Modern Spectroscopic Analysis, Modern Chromatographic Analysis.

1. Understand the various reaction chemical reactions, including reduction reactions, oxidation reactions, chemical reaction reactions, decomposition reactions, acid-base neutralization reactions, etc. In chemical reactions, we must firmly grasp the change of valency, and knowing this, I believe that it is not difficult to react.

2. Doing as much experimental practice as possible is the only criterion for testing the truth, so experiments also account for a considerable proportion. You need to understand the use of some experimental equipment, such as: condenser tubes, test tubes, iron frames, alcohol, etc.

In addition, when doing experiments, you must pay attention to your own safety. 3. Before class, the teacher will often talk about the difficult and easy to mix points, and before the teacher speaks, you must prepare for the preview. 4. Connect the knowledge points of life and learning, and connect them with actual life.

For example, iron rusts because iron undergoes a slow oxidation reaction in the air.

1. Master the basic principles of chemistry: Since "Analytical Chemistry Yuan Qi Huili" involves the basic theories of the entire field of chemistry and covers a wide range, the textbook is only the most basic content, and there is still a lot of space for students to think and imagine. Therefore, when reading a book, you should be curious about every sentence in the book, so that you can understand more and more of the content contained in the book.

2. Establish the correct concept of "quantity": When learning the analytical chemistry course eggplant bark after learning the chemistry without flutter machine, it is not easy to accept the method of analytical chemistry to deal with the chemical equilibrium of complex systems. The main problem is that analytical chemistry takes a different approach than inorganic chemistry when dealing with the chemical equilibrium of complex systems.

3. Pay attention to analytical chemistry laboratory courses: combine the knowledge learned with experimental exercises.

Learn chemical analysis well, and the knowledge of inorganic chemistry must be reviewed well. The volume analysis in chemical analysis is based on acid-base reaction, combination reaction, redox reaction, and precipitation reaction. At the same time, the factors that affect the complete completion of the reaction in the above reaction process must be considered.

Therefore, first, it is necessary to grasp the principles of various reactions, and the more complex ones are the coordination reaction and oxygen return reaction. Second, many students often find it difficult to calculate the content, but in fact, it is enough to clarify the different forms of determination - titration methods, and list the corresponding reaction formulas and derive the corresponding calculation formulas. Third, it is necessary to pay attention to the concept and application of significant figures, and to follow them in order to express the results correctly.

Analytical chemistry is a highly operational discipline, which understands theories in experiments and constantly uses theories to think about experimental process problems in experiments.

This is my previous one, say it again.

As a side note, if you want to learn it well, you must first establish an interest in analytical chemistry. Clarify the tasks of analytical chemistry and its important position in chemistry. Interest is the most important thing.

Sometimes it can be very annoying, the calculation is troublesome, you must calm down, be patient, when there is something to gain, build self-confidence, and the future will be much smoother.

Analytical chemistry has instrumental analysis and chemical analysis, but they are all required to be careful and careful, chemical analysis is more demanding for personal operation and judgment, and more requirements for personal hands-on ability and methods for the selection of their respective substances. Instrumental analysis is about understanding the principles of instruments and methods. To put it simply, it's more theoretical.

It's very simple, it's about the same as high school, and it's the foundation for later analytical measurements.

Learn the methods of analytical chemistry well:

1. The purpose of learning differentiation.

The purpose of learning differentiation is to master basic theories, methods, and experimental skills; Cultivate a rigorous work style and scientific attitude; Establish an accurate concept of quantity; Cultivate and train the quality of scientific research.

2. The requirements of learning differentiation.

a. Master the basic principles of analytical chemistry.

b. Establish a correct concept of "quantity".

c. Pay attention to analytical chemistry laboratory courses.

d. Preview before class, listen carefully in class, and take good notes.

e. Review after class, be good at summarizing, and do a good job in exercises.

3. Exam summary.

Analytical chemistry is mainly about paying attention to the question of quantity, which must be remembered and paid attention to from beginning to end, and also to pay attention to the unit.

Regarding learning, first listen to the lecture, but after listening to the lecture, it is very likely that you will not see the problem, that is, you must first look at the example questions, see which formula to use, and then do a few questions of this type, it is best to do all kinds of question types in a reference book, analytical chemistry is definitely not a day of assault!

To put it simply:

The mathematical basis of analytical chemistry is proportional or linear relations. All the work revolves around it. The first is how to find the linear relationship, the second is how to ensure the linear relationship, and the third is to ensure repeatability.

You can experience it.

I'm sorry for the university. , I don't know, I haven't gotten on it yet.

The system has its own energy and can do work externally as well as receive work from the outside, and the change here can be compared with free energy, i.e., g

g0, that is, the energy of the system is raised, that is, the outside world does work on the system, that is, it is not spontaneous.

2. There are many forms of work, the common ones are thermal and volumetric work, two kinds.

Heat, which is heat, is enthalpy, refers to the change in energy that does not do volumetric work.

Volumetric work, that is, the volume of the system can also change, expansion, that is, work done to the outside, and compression is the work that is affected by the outside, which can be measured by the change in entropy.

So, g = h -t s

h, is the enthalpy change, that is, the heat change of the system, h0, that is, endothermy, that is, the heat of the system increases, that is, the external body increases the heat work of the system.

t s is equivalent to volume work, s is the degree of chaos, but it can also be seen as related to volume, solid to liquid, to gas, s>0, that is, the volume increases, the work is done to the outside world, and it is related to the temperature, the temperature increases, the volume expands, and the work done to the outside world is more, then the energy of the system itself decreases, so it is the "-" sign.

And inorganic and analytical chemistry aren't too hard to find these days. Regarding finding specific inorganic and analytical chemistry, I suggest you take a look at inorganic and analytical chemistry here, the reason why the inorganic and analytical chemistry here is relatively complete, the inorganic and analytical chemistry network in other places may not be as comprehensive as the inorganic and analytical chemistry here, and you can find inorganic and analytical chemistry anywhere, because inorganic and analytical chemistry are easy to find, and inorganic and analytical chemistry are not too difficult to find now. As for finding specific inorganic and analytical chemistry, I suggest you take a look at inorganic and analytical chemistry here, because the inorganic and analytical chemistry here is relatively comprehensive, and the inorganic and analytical chemistry network in other places may not be as comprehensive as the inorganic and analytical chemistry here.
