NH (13.9) N N *Values <0 for H2O and DMSO, and values >14 for water and >35 for DMSO were extrapolated using various methods. D.H. Ripin, D.A. Evans pKa's of CH bonds in …

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 Carboxylic Acids Protonated Carbonyl …

2017年4月18日 · The pK a H of ammonia is 9.2, which measures the acidity of its conjugate acid, NH 4 (+). The pK a of ammonia itself is 38, which measures the equilibrium constant for …

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. The lower the pKa of a Bronsted acid, the more easily it gives up its proton. …
