브뢴스테드-로리 산 염기
The acid-base reaction class has been studied for quite some time. In 1680, Robert Boyle reported traits of acid solutions that included their…
산/염기 세기와 해리상수
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…
물: 브뢴스테드-로리 산 염기
The reaction between a Brønsted-Lowry acid and water is called acid ionization. For example, when hydrogen fluoride dissolves in water and…
pH 척도
Hydronium and hydroxide ions are present both in pure water and in all aqueous solutions, and their concentrations are inversely proportional as…
짝산-염기쌍의 상대적 세기
Brønsted-Lowry acid-base chemistry is the transfer of protons; thus, logic suggests a relation between the relative strengths of conjugate…
강산 용액과 강염기 용액
A strong acid is a compound that dissociates completely in an aqueous solution and produces a concentration of hydronium ions equal to the initial…
약산 용액
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…
약염기 용액
Some compounds produce hydroxide ions when dissolved by chemically reacting with water molecules. In all cases, these compounds react only partially…
산 혼합
The pH of a solution containing an acid can be determined using its acid dissociation constant and its initial concentration. If a solution contains…
산과 염기로서의 이온
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…
염용액의 pH 계산
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…
다양성자 산
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…
산 세기와 분자 구조
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…
루이스 산 염기
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…
적정을 사용하여 루이스 쌍의 특성화 와 함께 의 Situ 적외선 분광법
Lewis acid-activation of carbonyl-containing substrates is a fundamental basis for facilitating transformations in organic chemistry. Historically,…
작은 올리고머 형성 막 단백질의 침전 평형 : 펜타 머 안정성에 히스티딘 양성자의 효과
Analytical ultracentrifugation (AUC) can be used to study reversible interactions between macromolecules over a wide range of interaction strengths…
디페닐 에테르의 수산화를 위한 Pt/CNTs 촉매의 산도 튜닝
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…
