H2O --> OH- + H+ using the values of delta G nought values for liquid water, the hydroxide ion, and the H+ ion. Plug that value into the equation delta G nought = -RTlnK and you will get 7.0 x 10^-14. Most organic chemistry textbooks conjure up the 15.7 value in an attempt ...
2. pKa, also known as the acid dissociation constant or Ka value, is a specific equilibrium constant that represents an acid's ability to donate hydrogen ions.3. This equilibrium situation involves the transfer of a hydrogen ion (a proton) from an acid (HA) to water (H2O).4....

There will be the original amount of NH4 minus the amount NH4 which have given away an H atom to OH- to make H2O. the former posted calculations was wrong. Yes. Quote so how much OH- is now in the liquid? have all of this reacted? You can't ever use all OH- from the water, ...
This solution was augmented with 25% (v/v) 2H2O for field locking, and then 700 μl were transferred to a 5-mm NMR tube with a septum-lined screw cap (Wilmad catalog no. 535-TR-7). A 1-mm capillary tube was filled with 0.1 mm potassium fluoride in 100 mm potassium chloride, pH...

Values of pKa′ = 18.4 and 19.8 for the C(α)-proton of N(1′)-protonated HET and free HET, respectively, were calculated from the rate constants for catalysis by H2O and buffer bases. Values of ka = 2 × 1010 and 3 × 109m1s1 were assumed for diffusion-controlled protonation of ...
