1. THE SHIFTING OF AN EQUILIBRIUM: THE COMMON ION EFFECT Weak Acids and Weak Bases • • • Let us now examine weak acids and weak bases from an equilibrium point of view. In a solution of the weak acid, HC2H3O2, the following equilibrium exists: HC2H3O2 (aq) H+ (aq) + C2H3O2 (aq) To 3 mL of 0.10 M HC2H3O2 add a drop of methyl orange, then add 1 M NaC2H3O2 a few drops at a time, with mixing. Explain your observations in terms of the equilibrium equation and the common ion effect. Write the equilibrium equation and explain your observations in terms of the equilibrium equation and the common ion effect in your notebook.
