WebbThe added strong acid or base is thus effectively converted to the much weaker acid or base of the buffer pair (H 3 O + is converted to H 2 CO 3 and OH - is converted to HCO 3- ). The pH of human blood thus remains very near the value determined by the buffer pairs pKa, in this case, 7.35.

WebbThe Ka value for acetic acid at 25 degrees Celsius is equal to the concentration of hydronium ions raised to the first power times the concentration of acetate anions raised to the first power divided by the concentration of acetic acid raised to the first power, with water being left out of our equilibrium constant expression. Webb• The value of Ka or Kb is the strength of the acid or base. Large numbers are strong acids, small numbers are weak acids --A strong acid has a stronger tendency to donate a proton --A strong base has a greater tendency to accept a proton. • Ka is usually expressed in log.
