# Can neutralization be reversed?

So far, maybe it's just that my course isn't advanced enough, but I have never seen anything called 'neutralization constant'.

Any such reaction involving an acid and a base will be complete no matter the strength of either reactant.

Buffer works the same way. If the reaction is reversible then the buffet is not effective.

• I imagine by "neutralization constant" you mean the inverse of the autoionization constant. For water that would mean $\ce{H^+ + OH^- -> H2O},\ \ K=1.0 \times 10^{14}$. This massive constant is why even weak acids or bases completely dissociate and react when faced against a strong base or acid, respectively. Mar 16 '15 at 0:59
