Calculate the percent dissociation of the acid in each of the following solutions. a. 0.50 m acetic acid b. 0.050 m acetic acid c. 0.0050 m acetic acid d. use le châtelier’s principle to explain why percent dissociation increases as the concentration of a weak acid decreases. e. even though the percent dissociation increases from solutions a to c, the [h1] decreases. explain.
