Document Summary

K = ka (reactant acid) / ka (product acid) Ka = when something acts like an acid. Kb = when something acts like a base. + h2o h2co3 + oh- kb = 2. 3 x 10-8. Produce an acid, base or neutral solution based on the anions and cations. Neutral solutions = cations come from strong bases, anions come from strong acids. These salts contain cations of strong bases: Use table 7. 6: acid base properties of aqueous solutions of various types of salts. Mix: baking soda, nahco3, and vinegar, ch3cooh (aq) Write the major species in solution before acid-base reactions occur. The strongest acid is going to interact with the strongest base. Major species in solution before acid-base reactions occur: Use the ka chart to determine the strongest acid. Use the kb chart to determine the strongest base. The strongest acid reacts with strongest base. K = 1. 76 x 10-5 / 4. 3 x 10-7 = 40. 9.
