WebComparing Relative Strengths of Acids and Bases The stronger the acid, the larger its Ka value, thus the smaller its pKa value Stronger acids will have weaker conjugate bases with small Kb values The stronger the base, the larger its Kb value, thus the smaller its pKb value Stronger bases will have weaker conjugate acids with small Ka values WebJun 20, 2024 · if dS = 0, seems to be more tricky. In this case the acid and base concentrations are set by the water dissociation constant, Kw. The code needs to determine which array (cA or cB) has the higher value for the concentration. Then the concentration of the one with the lower value is calculated based on Kw and the higher concentration.
