pKb=11.73 (calculated from the pKa-value of hypophosphorous Acid : pKb = 14 -pKa)

Key value for chemical safety assessment

Additional information

From expert statement, the pKb of the substance is calculated from the pKa of hypophosphorous acid determined in a study according to guideline OECD 112 and GLP standard.

As the expert statement is well described, the study is considered as reliable without restrictions.
