Calculate the percent ionization of nitrous acid in a solution that is 0.241 M in nitrous acid (HNO₂)and 0.195 M in potassium nitrite (KNO₂). The acid dissociation constant of nitrous acid is 4.50 × 10^-4. A)44.7 B)0.229 C)13.5 D)2.11 × 10^-³ E)3.258

Question

Quizplus · Accepted Answer

The percent ionization can be calculated using the formula: % ionization = ([H⁺]/[HA]₀) × 100. Using the Henderson-Hasselbalch equation, we find [H⁺] and then calculate the percent ionization.
