WebNov 28, 2015 · Re: KOH as a Bronsted base. Since KOH is a strong base, it actually fits the definition of Arrhenius base since it dissociates to OH- ions. Then due to a high OH concentration, there will be a low pOH and therefore a high pH. But if we mix KOH with some weak acid like CH3COOH, then the proton transfer is clear: OH- + CH3COOH --> H2O + … WebAboutTranscript. When a weak acid and a strong base are mixed, they react according to the following net-ionic equation: HA (aq) + OH⁻ (aq) → A⁻ (aq) + H₂O (l). If the acid and base are equimolar, the pH of the resulting solution can be determined by considering the equilibrium reaction of A⁻ with water.
