cannot calculate the pH directly using uc rocess of establishing the equilibrium and In weak acids, we need to understand the how much acid dissociated and the calculate the strength of the acid based on + of these problems, we use ICE approach to concentration of [H+] at equilibrium. In most estimate the equilibrium concentration of (H) as the % of acid dissociated for any weak acid, Percent ionization of a weak acid is defined as the % of acid...
