Säuren und Basen

Bronsted-Lowry Säuren und Basen
Bronsted-Lowry Säuren und Basen
The acid-base reaction class has been studied for quite some time. In 1680, Robert Boyle reported traits of acid solutions that included their ability to ...
Säure-Basen-Stärken und Dissoziationskonstanten
Säure-Basen-Stärken und Dissoziationskonstanten
The relative strength of an acid or base is the extent to which it ionizes when dissolved in water. If the ionization reaction is essentially complete, ...
Wasser: A Bronsted-Lowry-Säure und Base
Wasser: A Bronsted-Lowry-Säure und Base
The reaction between a Brønsted-Lowry acid and water is called acid ionization. For example, when hydrogen fluoride dissolves in water and ionizes, ...
pH-Skala
pH-Skala
Hydronium and hydroxide ions are present both in pure water and in all aqueous solutions, and their concentrations are inversely proportional as ...
Relative Stärken von konjugierten Säure-Base-Paaren
Relative Stärken von konjugierten Säure-Base-Paaren
Brønsted-Lowry acid-base chemistry is the transfer of protons; thus, logic suggests a relation between the relative strengths of conjugate acid-base ...
Starke Säure- und Basenlösungen
Starke Säure- und Basenlösungen
A strong acid is a compound that dissociates completely in an aqueous solution and produces a concentration of hydronium ions equal to the initial ...
Schwach saure Lösungen
Schwach saure Lösungen
Few compounds act as strong acids. A far greater number of compounds behave as weak acids and only partially react with water, leaving a large majority of ...
Schwache Basislösungen
Schwache Basislösungen
Some compounds produce hydroxide ions when dissolved by chemically reacting with water molecules. In all cases, these compounds react only partially and ...
Mischungen von Säuren
Mischungen von Säuren
The pH of a solution containing an acid can be determined using its acid dissociation constant and its initial concentration. If a solution contains two ...
Ionen als Säuren und Basen
Ionen als Säuren und Basen
Salts with Acidic Ions Salts are ionic compounds composed of cations and anions, either of which may be capable of undergoing an acid or base ionization ...
Bestimmung des pH-Werts von Salzlösungen
Bestimmung des pH-Werts von Salzlösungen
The pH of a salt solution is determined by its component anions and cations. Salts that contain pH-neutral anions and the hydronium ion-producing cations ...
Polyprotische Säuren
Polyprotische Säuren
Acids are classified by the number of protons per molecule that they can give up in a reaction. Acids such as HCl, HNO3, and HCN that contain one ...
Säurestärke und Molekularstruktur
Säurestärke und Molekularstruktur
Binary Acids and Bases In the absence of any leveling effect, the acid strength of binary compounds of hydrogen with nonmetals (A) increases as the H-A ...
Lewis-Säuren und -Basen
Lewis-Säuren und -Basen
In 1923, G. N. Lewis proposed a generalized definition of acid-base behavior in which acids and bases are identified by their ability to accept or to ...
