Ionization steps of oxalic acid

Web5 aug. 2015 · In oxalic acid, the hydrogen oxalate ion and the oxalate ion (Which are conjugate bases in first and second dissociations) are resonance stabilized. The negative charge on oxygen atom is in conjugation throughout the molecule (with two pi bonds). Hence it is more stable. WebBecause of the very large range of acid strengths ( greater than 10 40), a logarithmic scale of acidity ( pK a) is normally employed.Stronger acids have smaller or more negative pK a values than do weaker acids. A discussion of acid-base terminology is available here. The pK a values given here are extrapolated for water at 25 ºC. Many of the pK a values …
