WebOct 27, 2024 · In short, the stronger the acid, the smaller the pKa value and strong acids have weak conjugate bases. pKa values describe the point where the acid is 50% dissociated (i.e. deprotonated). Below are tables that include determined pKa values for various acids as determined in water, DMSO and in the gas Phase. WebWe will therefore use Equation 7.1.21, the more general form of the Henderson-Hasselbalch approximation, in which “base” and “acid” refer to the appropriate species of the conjugate acid–base pair. We are given [base] = [Py] = 0.119 M and [acid] = [HPy +] = 0.234M. crossword the dancing couple painter jan https://olderogue.com
