Introduction: Physiological pH and chemical pKa are two sides of the same coin in defining the ionization of a drug in the human body.The Henderson-Hasselbalch equation and pH-partition hypothesis form the theoretical base to define the impact of pH-pKa crosstalk on drug ionization and thence its absorption, distribution, metabolism, …
The point where ph pka for bh+
Did you know?
Webb30 juni 2024 · Answer: a. the pH is only determined by the concentration of B and no titrant is added to the solution yet. b. when acid is added to the weak base B it is converted to conjugal acid BH+. WebbA base will give hydroxide ions in reaction with water. B (aq) + H2O (l) → HB+ (aq) + OH- (aq) From the pH we know pOH = 14 - 9.82 = 4.18. We can calculate now [OH-]. The [HB+] equals [OK-]. The actual concentration [B] = 0.1 - [HB+]. This three concentrations must be substituted in the equation of Kb to calculate the value of Kb. 9 Pete Gannett
