Calculate the percent ionization of nitrous acid in a solution that is 0.249 M in nitrous acid. The acid dissociation constant of nitrous acid is 4.50 × 10^-4. A)1.12 × 10^-4 B)0.0450 C)4.25 D)0.342 E)5.53

Question

Quizplus · Accepted Answer

Percent ionization is calculated using the formula: (sqrt(K_a / [HA]) * 100). For nitrous acid, K_a = 4.50 × 10^-4 and [HA] = 0.249 M. The percent ionization is approximately 4.25%.
