Rarely Tested

  • $$\alpha = \sqrt{\frac{K_a}{C}}$$
  • Concept: Determines the fraction of the total number of molecules of an electrolyte that split into ions in a solution.
  • Notation:
  • $$\alpha$$ = Degree of ionization;
  • $$K_a$$ = Acid dissociation constant;
  • $$C$$ = Molar concentration of weak acid.
