酸度系數 （英語： Acid dissociation constant，又名 酸解離常数，代號 Ka 、 pKa 、 pKa值），在 化學 及 生物化學 中，是指一個特定的 平衡常數，以代表一種 酸 解離 氫 離子 的能力 …

2017年10月27日 · In short, the stronger the acid, the smaller the pKa value and strong acids have weak conjugate bases. pKa values describe the point where the acid is 50% dissociated (i.e. …

pKa Scale. Definition of pKa. You can think of any molecule that has a proton on it as being an acid. They don't have to be very strong acids, but nonetheless they can behave as an acid. If …

2024年10月26日 · pKa即解离常数（dissociation constant），是水溶液中具有一定解离度的溶质的极性参数。 绝大多数的药物包含可电离的基团，多数为碱性的，也有部分为酸性。 只有极少 …

The pKa measures how tightly a proton is held by a Bronsted acid. A pKa may be a small, negative number, such as -3 or -5. It may be a larger, positive number, such as 30 or 50.

2010年9月29日 · We’ll go through the exact details of how to use pK a values to tell if an acid base reaction is favorable or unfavorable. pK a is the negative logarithm of the acid …

此数据由哈佛大学的David Ripin and David Evans收集，包括以下化合物的 pKa 。 Inorganic Acids Alcohols, Oximes, Hydroxamic Acids, and Peroxides

2014年6月22日 · Accurate and well-curated experimental pKa data of organic acids and bases in both aqueous and non-aqueous media are invaluable in many areas of chemical research, …

What is pKa? pKa is a value that indicates how weak or powerful an acid is in simple terms. The pKa of a strong acid is less than zero. pKa is the negative log base ten of the Ka value, to be …

Acid-dissociation is a reversible reaction described by an equilibrium constant (Keq) which, for the ionization of acids is denoted as Ka. The p K a is derived from the Ka by taking its negative …
