布朗斯特-劳里的酸和碱
The acid-base reaction class has been studied for quite some time. In 1680, Robert Boyle reported traits of acid solutions that included their…
酸碱强度和解离常数
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…
水: 布朗斯特-劳里的酸和碱
The reaction between a Brønsted-Lowry acid and water is called acid ionization. For example, when hydrogen fluoride dissolves in water and…
pH值
Hydronium and hydroxide ions are present both in pure water and in all aqueous solutions, and their concentrations are inversely proportional as…
共轭酸碱对的相对强度
Brønsted-Lowry acid-base chemistry is the transfer of protons; thus, logic suggests a relation between the relative strengths of conjugate…
强酸和碱溶液
A strong acid is a compound that dissociates completely in an aqueous solution and produces a concentration of hydronium ions equal to the initial…
弱酸溶液
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…
弱碱溶液
Some compounds produce hydroxide ions when dissolved by chemically reacting with water molecules. In all cases, these compounds react only partially…
酸的混合物
The pH of a solution containing an acid can be determined using its acid dissociation constant and its initial concentration. If a solution contains…
离子作为酸和碱
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…
确定盐溶液的 pH 值
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…
多质子酸
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…
酸强和分子结构
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…
路易斯酸和碱
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…
使用滴定与原位红外光谱相结合,对刘易斯对进行特征化
Lewis acid-activation of carbonyl-containing substrates is a fundamental basis for facilitating transformations in organic chemistry. Historically,…
小型低聚物形成膜蛋白的沉降平衡:组氨酸质子对五聚体稳定性
Analytical ultracentrifugation (AUC) can be used to study reversible interactions between macromolecules over a wide range of interaction strengths…
调整二苯醚氢氧化的Pt/CNT催化剂的酸度
We herein present a method for the synthesis of HNbWO6, HNbMoO6, HTaWO6 solid acid nanosheet modified Pt/CNTs. By varying the weight of various solid…
