The document provides the dissociation equations, hydrolysis equations, and predicted acidic, basic, or neutral properties for several salts, including KCl, KNO3, NaCl, NaNO3, and NaC2H3O2. It predicts that KCl, KNO3, NaCl, and NaNO3 will be neutral since they produce a salt of a strong acid and strong base upon hydrolysis. NaC2H3O2 is predicted to be basic since it produces a salt of a weak acid and strong base upon hydrolysis.

1. Concept Check: write down the dissociation equation and hydroiysis in water and predict their
acidic, basic, or neutral properties with theirestimated K,or K, constants for the following salts.
