(a) Interpretation: The percent dissociation of 0 .050 M HF needs to be determined. Concept introduction: For a weak acid say HA, the percent dissociation is a ratio of concentration of dissociated HA to initial amount of HA multiplied by 100 . By increasing the value of K a , the value of percent dissociation will be also increase. The strong acid completely dissociated in solution ( 100 % ) . The value of K a is large for strong acids. For weak acids the value of percent dissociation changes by changing the concentration value.
