The basicity constant is related to the acidity constant of the conjugate acid (in this case OH-) by the equation: pKa+ pKb= 14 So if the pKbof oxide is -38, that would make the pKaof hydroxide ion equal to 52! Of course this is a very rough approximation but it makes sense, sin...

Rate constants for C(α)-proton transfer from racemic 2-(1-hydroxyethyl)thiamin (HET), 2-(1-hydroxyethyl)oxythiamin (oxy-HET), and several 2-(1-hydroxyethyl)-3-R-4-methylthiazolium ions catalyzed by H2O, hydroxide ion, and various oxygen-containing and amine buffers in the pH range 2–...
Pure water has a low conductivity and is only slightly ionised however does Water dissociate slightly into Hydronium ions and hydroxide ions: or The concentration of H+ and OH- ions, which are equal, are 1x 10-7 ions per litre The equilibrium constant (or ion product ) for the ...
The catalytic activity and protein environment of CA can be understood by studying complexes having structural resemblances to it. Deprotonation of zinc bound water, generating hydroxide ion on the active site of the catalyst is shown to be the rate limiting step of the catalytic mechanism ...
The first-order rate constants for hydrolysis of 3-C-methyluridylyl(2,5)- and -(3,5)adenosine and the corresponding native dinucleoside monophosphates (2,5- and 3,5-UpA) have been determined as a function of hydroxide-ion concentration (0.025 - 7 M) at 25掳C. In addition to the ...

Hydrochloric acid (HCl) is a strong Brønsted–Lowry acid, whereas sodium hydroxide (NaOH) is a strong Brønsted–Lowry base. Mathematically, pKa is defined as the negative logarithm of the acid dissociation constant, Ka. Before going further, let’s have a quick refresher on Ka. ...
How to calculate pKeqfor organic acid-base reactions As mentioned above, the pKais the negative logarithm of theKaa. So, the pKeqwill be the negative logarithm of the Keq. But pKeqcan obtain from this formula: We will apply it to the previous example: ...
