WebSo that this reacting would result. This year we have 0.20 moles. So the weak acid concentration would decrease by 0.10 moles. However, the conjugated based concentration would increase by 0.10 moles as a result of this reaction. So we would have both weak acid and conduct based in our reaction. So this would also form a buffer system.
