Web11 Nov 2024 · pK a is the negative base-10 logarithm of the acid dissociation constant (K a) of a solution. pKa = -log 10 K a The lower the pKa value, the stronger the acid. For example, the pKa of acetic acid is 4.8, while the pKa of lactic acid is 3.8. Using the pKa values, one can see lactic acid is a stronger acid than acetic acid. WebVmin is also proportional to the pKa values of the conjugate acids of PR3, viz., [PR3H]+. Further, the ΔE values of the reaction Ni(CO)3 + PR3 → Ni(CO)3PR3 and ScH3 + PR3 → ScH3PR3 are also linearly proportional to the Vmin values. ...
