Calculate the percent ionization of nitrous acid in a solution that is 0.260 M in nitrous acid. The acid dissociation constant of nitrous acid is 4.50 × 10^-4. A)1.17 × 10^-4 B)0.0450 C)4.16 D)0.314 E)5.78

Question

Quizplus · Accepted Answer

Percent ionization is calculated using the formula: % ionization = ([H⁺]/[HA_initial]) × 100. Using the ICE table and the given Ka, [H⁺] is found to be approximately 0.0108 M. Thus, % ionization = (0.0108/0.260) × 100 ≈ 4.16%.
