theoretical knowledge, but also practical skills. In this article, we will give detailed
information about the process of learning complex compounds, its importance and place
in the educational process.
Key words: complex compounds, chemistry, metal ions, ligands, new compounds,
practical skills, education.
INTRODUCTION
Complex compounds are chemical compounds formed between metal ions and
ligands. Ligands are molecules or ions that bind to metal ions and surround them. They
change the chemical properties of metal ions and form new compounds. For example, a
copper-ammonia complex is formed as a result of the combination of copper (Cu) ion
with ammonia (NH₃) ligands. This process makes it easier for students to understand
chemical reactions. Studying complex compounds in chemistry classes is important for
students. During the lessons, students will have the opportunity to learn how to
synthesize complex compounds, study their properties and observe their chemical
reactions. This process helps to develop chemical thinking among students.
MATERIALS AND METHODS
Practical experiments play an important role in the process of studying complex
compounds. Students perform various experiments to observe the bonds between metal
ions and ligands. For example, students synthesize color complex compounds and study
their colors and properties.[1]
These experiments make it easier for students to understand complex compounds
and allow them to see their chemical properties in action. Theoretical knowledge is also
important in the process of studying complex compounds. Students learn theoretical
knowledge about how to identify complex compounds, their structure and properties.
This knowledge provides students with a deep understanding of chemistry and inspires
them to pursue scientific research in the future. Complex compounds play an important

role not only in chemistry, but also in biological processes. Some complex compounds,
for example, metal complexes, perform important functions in the div. Students will
learn the role of these complexes in the div and their use in medicine. It provides
students with an in-depth understanding of the practical applications of chemistry. Also,
complex compounds help to understand environmental issues. Some complex
compounds, such as heavy metal complexes, can have harmful effects on the
environment. Students will have the opportunity to learn about these issues and help
develop ways to protect and use the environment safely.[2]
RESULTS AND DISCUSSIONS
The process of studying complex compounds creates an opportunity for students to
feel themselves as scientific researchers. They will have the opportunity to conduct
scientific research by synthesizing new complex compounds, studying their properties
and observing their chemical reactions. This process helps students develop scientific
thinking and problem solving skills. The process of studying complex compounds is
important in chemistry, and various practical experiments are carried out in this process.
These experiments help students gain a deeper understanding of complex compounds
and allow them to see their chemical properties in action. First of all, experiments on the
synthesis of complex compounds are important. Students participate in the process of
preparing complex compounds using various metal ions and ligands. For example, the
process of preparing a copper-ammonia complex using copper sulfate and ammonia will
be interesting and instructive for students. In this process, students observe each step of
the synthesis process and study the reaction conditions. Color observation experiments
are also important. Complex compounds are often colored, and their colors depend on
the bonds between ligands and metal ions.[3]
Students learn about the structure and properties of this complex by forming a
complex with iron (III) ions and thiocyanate ions and observing the color of this
complex. Color variations create interesting experiences for students in the process of

learning complex compounds. Experiments to observe chemical reactions also take their
place.Students conduct various chemical reactions with complex compounds and study
their properties in reactions. For example, by testing complex compounds in acidic or
basic environments, students have the opportunity to study their stability and reactivity.
Through spectroscopic analysis experiments, students learn to analyze complex
compounds using UV-Vis spectroscopy. Studying the absorption spectrum of
complexes using this method provides important information about their structure and
properties. Students gain a deeper understanding of complex compounds by analyzing
spectroscopic data. Stability analysis is also an important experience. Students conduct
experiments under various conditions to study the stability of complex compounds. In
this process, the complex is broken down or transformed into new compounds. Students
gain a deeper understanding of complex compounds by studying the effects of changes
in pH or temperature. In the process of studying the effect of ligands, students form
complex compounds with various ligands and study the effect of ligands on the binding
of metal ions.[4]
This process creates fun and educational experiences for students. Comparing the
properties of complexes prepared using different ligands provides important knowledge
for students. Finally, experiments to study biological effects are also important. Some
complex compounds play an important role in biological processes. Students conduct
experiments to study the biological activity of metal complexes. For example, studying
the relationship of iron complexes with hemoglobin will be interesting and useful
experiences for students. In general, hands-on experiences during the study of complex
compounds help students gain a deeper understanding of the field. Each experience
provides an opportunity for students to develop new knowledge and skills. This process
helps to learn interesting and important aspects of chemistry.[5]

CONCLUSION
In general, the study of complex compounds in chemistry classes is an important
and interesting process for students. This process helps not only to learn chemical
knowledge, but also to develop practical skills. By studying complex compounds,
students gain in-depth knowledge in the field of chemistry and have the opportunity to
conduct scientific research in the future. Also, this process helps to develop
environmental awareness and environmental protection among students. The study of
complex compounds in chemistry classes will play an important role in the development
of new technologies and drugs in the future.
