Web7 mei 2013 · Since most drugs are either a weak acid or a weak base, when they are dissolved in body fluids, some or all of the drugs molecules become ionized/unionized. This is illustrated below in the standard equations for the ionization of a weak acid and weak base: Weak acid ionization: HA = H+ + A– Weak base ionization: BH = H+ + B– WebThe calculus first calculates the pK a, which is the ionization constant of the ammonium ion. To calculate the pK a value of the sample, we use the equation: pKa = 0.09018 + 2727.92/T pK a = 0.09018+2727.92/T. where T is the temperature in Kelvin.
