Brønsted-Lowry 酸和碱
Brønsted-Lowry 酸和碱
In 1923, the Brønsted–Lowry definition of acids and bases was proposed by Johannes Brønsted and Thomas Lowry. According to this theory, a ...
路易斯酸和碱
路易斯酸和碱
This lesson delves into Lewis acids and bases in the context of the octet rule for electron-deficient compounds. Here, the concept is discussed, ...
酸和碱:<em>K</em><sub>a</sub>、p<em>K</em><sub>a</sub> 和相对强度
酸和碱:Ka、pKa 和相对强度
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 ...
酸碱反应中的平衡位置
酸碱反应中的平衡位置
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 ...
分子结构和酸度
分子结构和酸度
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 ...
流平效应和非水性酸碱溶液
流平效应和非水性酸碱溶液
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 ...
溶剂化效应
溶剂化效应
An understanding of the solvating effect helps rationalize the relation between solvation and acidity of the compound. In addition, this also explains the ...
