How do Lewis bases/acids affect the pH of a solution? If they are bases, they should cause the OH- concentration to increase or the H+ concentration to decrease. If they are acids, the opposite. However, I don't see how they can do that if they are simply electron acceptors/donors. Can someone explain the mechanism?
