Unformatted text preview: OH, with K = 1014.0. The mole fraction of H2O is always assumed to be ~1.0, so: H2O ↔ H+ + OH Example. A solution is at pH 8.3. What is the OH concentration, including units? Hydrochloric acid Hypochlorous acid Acetic acid Carbonic acid ACIDS AND BASES • Acids are species that increase the H+ concentration (and therefore lower the pH) in solution. Many acids do this by releasing H+. Strong acids release all the available H+; weak acids release only a fraction of the available H+. • • • • • Phosphoric acid ACIDS AND BASES Sodium chloride Sodium hypochlorite Potassium acetate Sodium carbonate Sodium bicarbonate Potassium phosphate • The species that has lost the H+ is capable of binding...
