### Question Asked by a Student from EXXAMM.com Team

** Q 1260391215. ** `0.010` `M` solution of an acid `HA` freezes at `–0.0205°C`. If `K_f` for water is `1.860` `K` `kg` `mol^(–1)`, find the ionization constant of the conjugate base of the acid. (assume `0.010` `M` = `0.010` `m`)

Use formula: `ΔT_f` (normal) `= K_f m`
