Citric acid proton affinity
WebSep 20, 2024 · What makes Citrate or Citric Acid an acid? As far as I know, an acid is something that gives off a proton or hydrogen ion H +. There are three C O O −, which I think is a carboxyl group, that lacks H +. They seem to rather demand a hydrogen ion from its environment than donate one, which make it basic and not acidic. WebLook for the Total energy (Hartree) in the output. The total energy of the proton should be close to E (H + ) = 0.2407 Hartree. The proton affinity is computed as PA = E (Ac - ) + E (H + ) - E (HAc), resulting in a final proton affinity of 0.5704 Hartree, or 357.93 kcal/mol. We leave it as an example to calculate the PA with DFTB2 (SCC-DFTB ...
