A chemist prepared aqueous solutions of two weak acids: solution A is butyric acid (HC3H8CO2), and solution B is nitrous acid (HNO2). At 25°C, the acid-dissociation constant (Ka) for butyric acid is 1.5 ✕ 10−5 and the base-dissociation constant (Kb) for the nitrite ion (NO2−) is 1.8 ✕ 10−11. Determine the following. (a) the Ka value for nitrous acid (HNO2) (b) the Kb value for the butyrate ion (C3H8CO2−)
Consider two aqueous solutions of nitrous acid (HNO2). Solution A has a concentration of (HNO2] = 0.25 M and solution B has a concentration of (HNO2] = 1.55 M.
