Question

Hexanoic acid (HC6H11O2) is a weak acid that dissociates in water as follows. HC6H11O2(aq) + H2O(l) equilibrium reaction arrow H3O+(aq) + C6H11O2−(aq) The acid-dissociation constant (Ka) for hexanoic acid is 1.4 ✕ 10−5. Calculate the percent ionization (percent dissociation) if the initial concentration of hexanoic acid was 0.24 M.
