Kw acid base

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. WebTo begin, the idea of weak acids and bases is explored along with the equilibrium constants associated with their ionization in water and how the value of the equilibrium constant is …
