1) This document discusses ionic equilibria, specifically the autoionization of water and the pH scale. It defines key terms like ionic product of water (Kw), pH, and pOH. 2) Salts can undergo hydrolysis when dissolved in water. Salts of strong acids and bases do not hydrolyze and are neutral. Salts of strong acids and weak bases hydrolyze to produce H3O+ ions, making the solution acidic. Salts of weak acids and strong bases hydrolyze to produce OH- ions, making the solution basic. 3) For salts of weak acids and bases, the solution can be acidic, basic, or neutral depending on whether the Ka
