Achemist prepared aqueous solutions of two weak acids: solution a is hydrazoic acid (hn3), and solution b is propanoic acid (hc2h5co2). at 25°c, the acid-dissociation constant (ka) for hydrazoic acid is 2.5 ✕ 10−5 and the base-dissociation constant (kb) for the propanoate ion (c2h5co2−) is 7.8 ✕ 10−10. determine the following. (a) the ka value for propanoic acid (hc2h5co2) (b) the kb value for the azide ion (n3−) (c) the stronger acid between hydrazoic acid and propanoic acid hydrazoic acid propanoic acid (d) the stronger base between the azide ion and the propanoate ion azide ion
