phosphate
In chemistry, a salt or ester of phosphoric acid. Phosphates are important nutrients for plants and are therefore used in fertilizers, but also in detergents and as food additives.
Hohe Konzentrationen von Phosphat in Seen können zu übermäßigem Algenwachstum führen.
High concentrations of phosphate in lakes can lead to excessive algae growth.
'Phosphat' (phosphate) is a technical term from chemistry. It is mainly used in scientific, technical, or environmental contexts, for example in agriculture or water analysis.
Der Phosphatgehalt im Abwasser wird streng kontrolliert.
The phosphate content in wastewater is strictly monitored.
In chemistry, the ending '-at' often signals the salt of an acid whose name ends in '-säure' (acid). 'Phosphat' (phosphate) is derived from 'Phosphorsäure' (phosphoric acid), just as 'Sulfat' (sulfate) is derived from 'Schwefelsäure' (sulfuric acid).
Die chemische Formel für viele Phosphate enthält das PO₄-Ion.
The chemical formula for many phosphates contains the PO₄ ion.
Common combinations describe function or concentration. Typical phrases are 'reich an Phosphat' (rich in phosphate), 'phosphatfreies Waschmittel' (phosphate-free detergent), or 'hoher Phosphatgehalt' (high phosphate content).
Dieser Dünger ist besonders reich an Phosphat und fördert das Wurzelwachstum.
This fertilizer is especially rich in phosphate and promotes root growth.
phosphorus
'Phosphor' and 'Phosphat' are closely related chemically, but they are not the same thing. 'Phosphor' is a chemical element. 'Phosphat' is a chemical compound, more specifically a salt or ester of phosphoric acid. Both words occur in contexts involving plants, fertilizers, and nutrients, so they can easily be confused. When referring to the element itself, you say 'Phosphor'. When referring to substances in fertilizer, detergents, or food additives, 'Phosphat' is often more precise.
Dieses Waschmittel enthält kein Phosphat.
This detergent does not contain any phosphate.
Im Chemieunterricht erklärt die Lehrerin, warum Phosphor für Lebewesen wichtig ist.
In chemistry class, the teacher explains why phosphorus is important for living things.
