Description of key information

pKa values for first dissociation are in the range 14.9-15.1 for the main organic constituents

Key value for chemical safety assessment

pKa at 20°C:
15

Additional information

Such a values indicates that dissociation of constituents would not occur under any conceivable environmental conditions. For the sodium acetate component, as it is ionic, 100% dissociation in water is assumed.
