Web1 day ago · Strong acids have a high value for acid dissociation constant (Ka) and a low value for logarithmic constant (pKa). For example, the Ka and pKa value for H2SO4 is 1 X 103 and -3, respectively. The point to be noted here is that even when H2SO4 is a diprotic acid its Ka and pKa values are calculated only for the first dissociation i.e. one proton.
