Likewise, if robust alkali is additional towards the combination, the hydrogen ion concentration decreases by below the amount envisioned for the amount of alkali extra. In Determine one, the result is illustrated through the simulated titration of the weak acid with pKa = 4.seven. The relative concentration of undissociated acid buffer solutions used in pharma is proven in blue, and of its conjugate base in purple.
