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`)
A

`9.0 × 10^(–12)`

B

`1.1 × 10^(–4)`

C

`1.1 × 10^(–3)`

D

`9.0 × 10^(–11)`

HINT

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