vízösszetétel

Vízösszetétel refers to the chemical composition of water. Pure water, chemically H₂O, consists of two hydrogen atoms bonded to one oxygen atom. However, natural water sources are rarely pure and contain dissolved substances, making their composition more complex. These dissolved substances can include minerals, salts, gases, and organic matter. The specific composition of water varies greatly depending on its origin and history.

Surface waters, such as rivers and lakes, often contain dissolved minerals from rocks and soil, as well as organic compounds from decaying vegetation and biological activity. Groundwater can also be rich in dissolved minerals, often differing from surface water due to longer contact with geological formations. Seawater has a very high concentration of dissolved salts, primarily sodium chloride.

The analysis of water composition is crucial for various purposes, including assessing its suitability for drinking, irrigation, industrial use, and understanding ecological health. Common components analyzed include pH, dissolved oxygen, nitrates, phosphates, heavy metals, and various ions like calcium, magnesium, and potassium. Understanding these components helps in managing water resources and protecting environmental quality.
