WebMay 6, 2016 · Hydrofluoric acid, #"HF"#, is a weak acid that does not ionize completely in aqueous solution to form hydronium cations, #"H"_3"O"^(+)#, and fluoride anions, #"F"^(-)#.. More specifically, the acid is partially ionized in aqueous solution, the extent of ionization depending on the value of the acid dissociation constant, #K_a#.. The equilibrium that … WebAs we would expect for a weak acid, the percent dissociation is quite small. However, for some weak acids, the percent dissociation can be higher—upwards of 10% or more. For example, with a problem involving the percent dissociation of a 0.100 M chloroacetic acid, we cannot assume x is small, and therefore use an ICE table to solve the problem.
