Doxofylline Pka value is about 9.8.
The pKa value for Potassium Phosphate is 7.2.
It is around pKa=13
pKa = 15
for H3PO4 pKa = 2.15 for NaH2PO4 pKa = 7.2 for Na2HPO4 pKa = 12.4
0.2 is the pKb for sodium Hydroxide not the pKa the pKa is 13.8
By following + or - 2 pH to the pKa value
The pka of a protonated ether (the conjugate acid) is about -3.5
The pKa of HSO4- (the second pKa of H2SO4) is 1.92. The Ka is thus 0.0120
The conjugate acid is Hydrogen (H2), the pKa of which is 35.
eftriaxone sodium has pKa values of 3, 3.2, and 4.1.
if Pka value is more for acidic drug,best side for absorption will be throughout the G.i.Tract.
actual pka of betaxolol is 9.4 but observed is 9.38
Sodium chloride, NaCl, is not an acid so it does not have a Ka or pKa value. Sodium chloride is a neutral salt.
A pKa value is a measurement used for bases and acids. The measurement pH applies to hydronium ion concentrations that are in a solution, whereas pKa only applies to determining the amount of dissociation an acid wants to do in a solution.
~13. Evidence: t-butoxide (pKa ~18) can deprotonate it to form dichlorocarbene.
A weak acid has a pKa value in the approximate range −2 to 12 in water.
pKa = 6.36 of carbonic acid to HCO3-
naphthalene is neutral.
