The episode defines strong acids and strong bases as those that completely ionize (dissociate) in water, meaning 100% of the molecules break apart. This strength is independent of concentration. Memorizing the few common strong acids (like HCl and H2SO4) and strong bases (Group 1 and 2 hydroxides) is critical. Because they ionize fully, the concentration of the strong acid or base directly equals the concentration of H+ or OH-, simplifying pH calculations.
