Acidi e basi

Acidi e basi di Brønsted-Lowry
Acidi e basi di Brønsted-Lowry
In 1923, the Brønsted–Lowry definition of acids and bases was proposed by Johannes Brønsted and Thomas Lowry. According to this theory, a ...
Teoria acido-base di Lewis
Teoria acido-base di Lewis
This lesson delves into Lewis acids and bases in the context of the octet rule for electron-deficient compounds. Here, the concept is discussed, ...
Acidi e basi: <em>K</em><sub>a</sub>, p<em>K</em><sub>a</sub> e forze relative
Acidi e basi: Ka, pKa e forze relative
This lesson delves into a critical aspect of the relative strengths of acids and bases. The strength of an acid is evaluated by the acid dissociation into ...
Posizione di equilibrio nelle reazioni acido-base
Posizione di equilibrio nelle reazioni acido-base
In any solution, the value of pKa indicates whether an acid is completely dissociated or not. A negative pKa corresponds to a stronger acid, whereas a ...
Struttura molecolare e acidità
Struttura molecolare e acidità
An acid can be deprotonated to form a conjugate base or an anion. If the produced anion is more stable, then the acid is stronger. On the contrary, if the ...
Effetto livellante e soluzioni acido-base non acquose
Effetto livellante e soluzioni acido-base non acquose
This lesson defines the leveling effect in acidic and basic solutions and its role in aqueous and non-aqueous solutions. It is essential to understand the ...
Effetti della solvatazione
Effetti della solvatazione
An understanding of the solvating effect helps rationalize the relation between solvation and acidity of the compound. In addition, this also explains the ...
