The pKa value for an acid is a logarithmic scale indicating its dissociation constant. This value is obtained through negative base-10 logarithmic calculations and is directly related to the thermodynamics of the dissociation reaction. More specifically, it is directly proportional to the standard Gibbs free energy change for the reaction. Therefore, an acid with a lower pKa value indicates a stronger acid with a higher tendency to donate a proton in a chemical reaction. Conversely, an acid with a higher pKa value indicates a weaker acid with a lower tendency to donate a proton in a chemical reaction.Can you provide the pka value for this molecule?
