PKa for hydrogen peroxide is 11.7 concerning the first acid (couple H2O2/HO2-). But what is the pKa value for the second acid (couple HO2-/O22-) ?

pKa  H2O2 / HO2- = 11.7 pKa HO2- / O22- = ? I guess it is very basic perhaps around 20? I would like to have a true value and if possible a reference. Thanks
