It is 29.8 (Ref. J. Org. Chem, 1980, 45, 3295).
The pKa of sulfonic acid is < 0
The conjugate acid is Hydrogen (H2), the pKa of which is 35.
The pKa of HSO4- (the second pKa of H2SO4) is 1.92. The Ka is thus 0.0120
15,7
the pH of ethanol can be calculated using its pKa value (pKa 15.9) and the Henderson-Hasselbalch equation. pH = pKa - log [AH/A] where [AH/A] the ratio of disassociated versus undisassociated species in solution.
It is 29.8 (Ref. J. Org. Chem, 1980, 45, 3295).
ethanol does not dissociate as much in solution as much as HCl , look up there pka values in future
pKa=40
how do you calculate pKa
pKa=2.86
pKa = 15
It is around pKa=13
Doxofylline Pka value is about 9.8.
yes ethanol is a base.its chemical formula is C2H5OHthe reason it is basic is because of the hydroxide ion attached to the end of the hydrocarbon and it registers 7.33 on the pH scaleB.S.
pKa (dissociation constant) is variable with temperature.
The pka of a protonated ether (the conjugate acid) is about -3.5
