Maleic acid is a weak diprotic acid with : pKa1 = 1.87 pKa2 = 6.07 A 10.00 mL solution of 0.1000 M maleic acid is titrated with 0.1000 M NaOH. This content was accessible as of December 29, 2012, and it was downloaded then by Andy Schmitz in an effort to preserve the availability of this book. This enzyme catalyses isomerization between fumarate and maleate. When a compound gives up a proton, it retains the electron pair that it formerly shared with the proton. To find the Kb value for a conjugate weak base, recall that. The higher the pKa of a Bronsted acid, the more tightly the proton is held, and the less easily the proton is given up. 0.1000 M NaOH.

The weaker something is as a source of protons, the stronger its conjugate is as a proton sponge. This is Appendix C: Dissociation Constants and pKa Values for Acids at 25C, appendix 3 from the book Principles of General Chemistry (v. 1.0). pKa (overall) is the negative log of the overall acidity constant for the overall ionization reaction of the polyprotic acid.

Is that a very, very, very, very weak acid? Low pKa means a proton is not held tightly. It is certainly a better source of protons than something with a pKa of 35. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. pKa1 = 1.87 these intramolecular hydrogen bonds make it difficult to release hydrogen to act as an acid. %PDF-1.6 % 0000002830 00000 n Chemical formulas or structural formulas are shown for the fully protonated weak acid. Going to a farther extreme, a compound from which it is very, very difficult to remove a proton is not considered to be an acid at all. Its chemical formula is HO 2 CCH=CHCO 2 H. Maleic acid is the cis -isomer of butenedioic acid, whereas fumaric acid is the trans -isomer.
