Description of key information

pKa = 4.32 -4.62

Key value for chemical safety assessment

pKa at 20°C:

Additional information

The pKa of the substance was retrieved by the literature in which the dissociation costants and limiting conductances of organic acids in water are reviewed. The pKa was found to be 4.62.

The pKa was also estimated by the use of ChemAxon in which the dissociation costant was predicted to be 4.32.

The dissociation costant obtained in the literature review is used for the chemical safety assessment as it is based on an experimental result In any case the predicted value is very close to the experimental value.
