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. WebAug 31, 2016 · 1 Answer. You are correct that the concentration of [ H X +] and [ O H X −] both vary based on the the composition (acid/alkaline) of the solution, but the remarkable thing is that their product does not. When [ H X +] goes up, [ O H X −] goes down, in the same proportion. The reason for this is that the K w represents the equilibrium ... straight no chaser a cappella
