Dissociation of na2co3

Figure 13.3.1: For a strong acid such as hydrochloric, its total dissociation means that [HCl] = 0, so the mass balance relationship in Equation 13.3.2 reduces to the trivial expression Ca = [Cl-]. Any acid for which [HA] > 0 is by definition a weak acid. Similarly, for a base B we can write.
