The disscociation constant of the reaction mass of calcium carbonate, calcium dihydroxide and calcium peroxide is not determined as the reaction mass is hydrolytically unstable. Instead, information on the relevant degradation products has been included.
The literature value available for the dissociation constant of hydrogen
peroxide at 25 °C is:
pKa = 11.62.
The literature value available for the dissociation constant of calcium
dihydroxide at 25 °C is:
pKb1 < 0 for Ca(OH)2
pKb2 = 1.2 for Ca(OH)+
