Every living thing on this earth can hardly survive without water. From humans, animals to plants and other microorganisms all need water. However, structure of water how? What is the chemical composition of water? very few people know. If you are interested in water-related information, then follow this article to discover together!
What is water?
Water is a chemical compound made up of oxygen and hydrogen with the chemical formula H2O. The structure of water has special physicochemical properties (such as dipoles, hydrogen bonding and density anomalies) water is a very important substance in many sciences and life. 70% of the Earth’s area is covered by water. But only 0.3% of all water on Earth is in sources that can be exploited for drinking water. Meanwhile, the human body is made up of 70% water. This shows that water is extremely important for all of us.
Besides “normal water” there is also heavy water and super heavy water. In these waters, the normal hydrogen atoms are replaced by the isotopes of deuterium and tritium. Heavy water has different physical properties from normal water, such as: higher melting point, higher boiling point, higher density, and different chemical properties.

What is a water molecule?
The structure of water is a combination of 2 hydrogen atoms (H +) and 1 oxygen atom (O2-) by hydrogen bonds. This combination gives water the chemical formula H2O.
The bond of 2 hydrogen atoms and 1 oxygen atom makes an angle of 104.5°. The molar mass of each water molecule is about 18 g/mol. Water molecules are extremely small, H + itself is also the smallest atom of the elements, so water is very easily absorbed through the skin.
The structure of water is formed by the bonding of 2 hydrogen and 1 oxygen
Properties of water molecules
Thus, we already know the structural formula of water and understand more about the composition of water. The next content we will learn about the properties of water molecules.
Color, shape, taste
Color: Pure water will be transparent, colorless. If we see color it is due to the reflection of light. For example, if you see blue ocean water, it is due to scattered or reflected light. The deeper the ocean water, the more blue light is scattered and reflected, resulting in blue water.
Shape: Liquid water molecules have no definite shape. In other words, water will have a shape depending on its container. And water in the solid state will form the shape of its container. Thanks to this structure of water, it is often used to make ice or ice cubes.
Taste: Pure water has no taste, so if we perceive a strange taste, it may be because the water has been mixed with other impurities. Or another way that can answer the phenomenon of water has a taste is due to the human body’s senses. For example, a sick person when drinking water will have a slightly bitter taste in the mouth because the body is not feeling well at this time.
In addition, if the water changes the natural pH, adding an abundance of minerals beneficial to the body, the water will have a characteristic taste. That’s why when we drink bottled mineral water, we will feel a very different taste than ordinary purified water.
Water is very important to all living things
Dipole of water
Based on the structure of water is 2 Hydrogen and 1 Oxygen, so the three-angle structural arrangement of these 3 molecules will not be equal. In addition, between Hydrogen and Oxygen, there is an opposite charge, causing the dipole phenomenon of water.
Also because of this difference in charge, water molecules are prone to vibrations and rubbing against each other when affected by electromagnetic waves. This problem creates water heating (microwave applications).
Hydrogen bonding
Due to the opposite charge between the Hydrogen and Oxygen atoms, water molecules are often attracted to each other by hydrogen bonds. However, this bond is not strong, it is easy to break. So, every fraction of a second, water molecules attract each other and then quickly separate to bond with other molecules, creating flexibility in motion.
Conductivity of water
Pure water does not conduct electricity. Water only conducts electricity when there are other impurities such as minerals, ions, salts, etc. It is the impurity molecules moving freely in this water that is the electrolyte that conducts the current.
The states of existence of water molecules
The state and structure of water can exist in 3 states: solid, liquid and gas. Water exists in a solid state when the temperature is below 0 degrees Celsius. The most common application of water in solids is the ice sheets of the Arctic and Antarctic. Therefore, water plays a very important role in climate regulation.
At temperatures above 0 degrees Celsius, water exists in liquid form, usually found in nature in seas, rivers, streams, ponds, canals, canals, etc. When the temperature rises, water evaporates and forms clouds. cloud.
As the clouds rise higher, the temperature of the clouds decreases and condenses into rain that falls into the sea, rivers, lakes, canals, canals… It is this natural phenomenon that has existed for many generations to form a cycle. Nature sustains life for the whole Earth.
Water exists in many different states
Structure of water
The properties and structure of water have similar characteristics. Specifically, the structure of water is shown through the following special factors.
Water molecule
The chemical composition of water is composed of two hydrogen atoms and one oxygen atom. Geometrically, the water molecule has a bond angle of 104.45°. Since the free electron pairs occupy a lot of area, this angle deviates from the ideal angle of the tetrahedron. Where, the length of the OH bond is 96.84 picometers.
Bipolarity
Oxygen is more electronegative than hydrogen, the triangular structure and charging of different parts of the conductive atoms have resulted in negative polarity in the oxygen atom and positive polarity in the hydrogen atom. This has caused the dipole of the water. Based on the two lone electron pairs of the oxygen atom, the VSEPR theory explained the angular arrangement of the two hydrogen atoms, the formation of the dipole moment, and thus the special properties of water.
Hydrogen bonding
Water molecules are linked together through hydrogen bonds. However, this is not a permanent link that only lasts for a fraction of a second. The water molecules then dissociate from this bond and bond with other water molecules.
The structure of water is quite simple, it is from Hydrogen and Oxygen
Water in life
All life on Earth needs and depends on water and the water cycle. Water has a decisive influence on climate and is the cause of weather phenomena. Water is an important component of biological cells and the medium in which basic biochemical processes, such as photosynthesis, take place.
More than 70% of the Earth’s area is covered by water. The provision of drinking water will be one of the biggest challenges facing humanity in the next few decades. Water is also the cause of one of the wars in the Middle East. So while we still have clean water to use, let’s cherish it and use it sparingly. We need to take practical actions to preserve and protect clean water for future generations.
Water is indispensable for all of us
Alkaline ionized water
Alkaline ionized water was discovered by the Japanese in the 20th century, specifically in 1965, and the Japanese Ministry of Health and Food Safety Authority issued the pharmaceutical announcement No. 763 recognizing the benefits of alkaline ionized water for human health. health. Specifically, the water after being electrolyzed from the alkaline ionized water purifier can exist in the form of micro-ions. It is alkaline in nature like green vegetables, rich in antioxidant hydrogen and rich in micro-minerals that bring many benefits to the human body.
Alkaline ionized water molecules exist in the form of micro-ions, only ⅕ times the size of ordinary water molecules, so they can easily penetrate into each cell quickly. The structure of alkaline ionized water helps promote better metabolism, blood circulation and detoxification.
The alkaline nature of alkaline ionized water helps to neutralize the excess acid that exists in the body. At the same time, it supports the treatment of many diseases caused by excess acid such as: stomach pain, stomach ulcers… Due to the structure of alkaline ionized water that brings many benefits to human health, it is now widely used. .
Alkaline ionized water has many health benefits
Thus, through the above article, we have clearly understood what a water molecule is, how water is structured and how water plays a role in our life. Hopefully from the above sharing, you have seen the importance of water for our body and activities in our lives. From there, treasure and save the daily clean water that we are using. Ocany wishes you peace and lots of joy in life.
