Bordwell pKa Table - Organic Chemistry Data
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. deprotonated). Below are tables that include determined pKa values for various acids as determined in water, DMSO and in the gas Phase.
Ammonium sulfate - Wikipedia
Ammonium sulfate (American English and international scientific usage; ammonium sulphate in British English); (NH 4) 2 SO 4, is an inorganic salt with a number of commercial uses. The most common use is as a soil fertilizer. It contains 21% nitrogen and 24% sulfur. The primary use of ammonium sulfate is as a fertilizer for alkaline soils.
Ammonium Sulfate | (NH4)2SO4 | CID 6097028 - PubChem
Ammonium sulfate is an inorganic sulfate salt obtained by reaction of sulfuric acid with two equivalents of ammonia. A high-melting (decomposes above 280℃) white solid which is very soluble in water (70.6 g/100 g water at 0℃; 103.8 g/100 g water at 100℃), it is widely used as a fertilizer for alkaline soils. It has a role as a fertilizer.

For strengths of organic acids see E. P. Serjeant and B. Dempsey (eds.), Ionization Constants of Organic Acids in Solution, IUPAC Chemical Data Series No. 23, Pergamon Press, Oxford, UK, 1979. The strength of a base is related to the pK a of its conjugate acid as pK b = 14 - pK a.

5.2: Acid Strength and pKa - Chemistry LibreTexts
If you are asked to say something about the basicity of ammonia (NH 3) compared to that of ethoxide ion (CH 3 CH 2 O-), for example, the relevant pK a values to consider are 9.2 (the pK a of ammonium ion) and 16 (the pK a of ethanol). From these numbers, you know that ethoxide is the stronger base.
