Beschreibung

Why talk about water? This vital compound is not equal to anything that gives life to humans, animals and plants; in short, to the entire ecosystem on Earth. How vital can it be to have water to drink to quench your thirst, to accompany our food and to make our environment livable? Many of us ignore the importance of this, either by squandering this common good, or by using it to do business. I will talk about how water is used in various continents and also how it is exploited by some for business, when a common good should belong to all and at low cost. Then we will also address the most important topic, pollution, which today destroys entire seas, lakes and rivers. Sources polluted by the neglect of man towards the environment and towards himself, yes, because those who ruin their territory will also ruin their own future and this is incomprehensible by all those who are defending this planet of ours. We will talk about the various types of water and their characteristics and their qualities. In short, a complete roundup that will bring more knowledge for this immense good that is water.

WATER AND MAN AN INSEPARABLE PAIR

INTRODUCTION

Why talk about water? This vital compound is not equal to anything that gives life to humans, animals and plants; in short, to the entire ecosystem on Earth. How vital can it be to have water to drink to quench your thirst, to accompany our food and to make our environment livable? Many of us ignore the importance of this, either by squandering this common good, or by using it to do business. I will talk about how water is used in various continents and also how it is exploited by some for business, when a common good should belong to all and at low cost. Then we will also address the most important topic, pollution, which today destroys entire seas, lakes and rivers. Sources polluted by the neglect of man towards the environment and towards himself, yes, because those who ruin their territory will also ruin their own future and this is incomprehensible by all those who are defending this planet of ours. We will talk about the various types of water and their characteristics and their qualities. In short, a complete roundup that will bring more knowledge for this immense good that is water.

CHARACTERISTICS

Water is a chemical compound whose molecular formula is H2O: This mysterious acronym means that every molecule of water is composed of an oxygen atom O and two hydrogen atoms H, the characteristics of water, an element of life that accompanies us at every moment of our day. We know that the water cycle is fundamental for our well-being, it allows the body to absorb and assimilate minerals, vitamins, amino acids and other substances, promotes digestive processes, allows the transport of nutrients to cells and oxygen to the brain, promotes the removal of toxins and metabolic waste, acts as a lubricant for joints and muscles. Essential for plants, animals and the proper functioning of the ecosystem. But are we sure we know why? And what are the characteristics that make it so unique? Today we want to brush up on school books and do a short chemistry review to discover together some of the incredible properties of this so special element. As we have seen before, water is composed of one oxygen atom and two hydrogen, H2O. any of the properties and characteristics of both natural water and mineral water make it special finding an explanation at the atomic level, in the seemingly simple bond between hydrogen and oxygen. The oxygen atom has two free electrons each shared with one of the two hydrogen atoms: the oxygen has an electronegative charge higher than that of hydrogen, allowing it to attract electrons more strongly. This peculiar characteristic creates a partial negative charge on the oxygen atom and a partial positive charge on the hydrogen atoms. This duality makes the molecule a dipole, a bit like a common stack that we use to make our electronic devices work. Thanks to this feature, water molecules attract each other through the formation of hydrogen bonds. Precisely because of this tendency of molecules to attract each other, water is an excellent natural solvent: this means that substances such as salts, once they are in the water, are surrounded by molecules that, thanks to their small size and polarization characteristics, are able to slip between one ion and the other, or between the single molecules of solute substance, surrounding
