Reaktionsstöchiometrie
Reaktionsstöchiometrie
A balanced chemical equation provides a great deal of information in a very succinct format. Chemical formulas provide the identities of the reactants and ...
Begrenzende Reagenzien
Begrenzende Reagenzien
The relative amounts of reactants and products represented in a balanced chemical equation are often referred to as stoichiometric amounts. However, in ...
Reaktionsausbeute
Reaktionsausbeute
The theoretical yield of a reaction is the amount of product estimated to form based on the stoichiometry of the balanced chemical equation. The ...
Allgemeine Eigenschaften von Lösungen
Allgemeine Eigenschaften von Lösungen
Many common substances around us exist as a solution, such as ocean water, air, and gasoline. All solutions are mixtures of substances that are composed ...
Lösungskonzentration und -verdünnung
Lösungskonzentration und -verdünnung
The relative amount of a given solution component is known as its concentration. Often, though not always, a solution contains one component with a ...
Elektrolyt- und Nicht-Elektrolytlösungen
Elektrolyt- und Nicht-Elektrolytlösungen
Substances that undergo either a physical or a chemical change in solution to yield ions that can conduct electricity are called electrolytes. If a ...
Löslichkeit ionischer Verbindungen
Löslichkeit ionischer Verbindungen
Solubility is the measure of the maximum amount of solute that can be dissolved in a given quantity of solvent at a given temperature and pressure. ...
Chemische Reaktionen in wässrigen Lösungen
Chemische Reaktionen in wässrigen Lösungen
Chemical substances interact in many different ways. Certain chemical reactions exhibit common patterns of reactivity. Due to the vast number of chemical ...
Niederschlagsreaktionen
Niederschlagsreaktionen
In a precipitation reaction, aqueous solutions of soluble salts react to give an insoluble ionic compound – the precipitate. The reaction occurs ...
Oxidations-Reduktions-Reaktionen
Oxidations-Reduktions-Reaktionen
Oxidation–Reduction Reactions Earth’s atmosphere contains about 20% molecular oxygen, O2, a chemically reactive gas that plays an essential ...
Oxidationszahlen
Oxidationszahlen
In redox reactions, the transfer of electrons occurs between reacting species. Electron transfer is described by a hypothetical number called the ...
Säuren, Basen und Neutralisationsreaktionen
Säuren, Basen und Neutralisationsreaktionen
An acid-base reaction is one in which a hydrogen ion, H+, is transferred from one chemical species to another. Such reactions are of central importance to ...
Synthese- und Zersetzungsreaktionen
Synthese- und Zersetzungsreaktionen
Synthesis and decomposition are two types of redox reactions. Synthesis means to make something, whereas decomposition means to break something. The ...
