Report Abuse. 1  E. NaF will form a basic solution . F-1 is the conjugate base of the weak acid HF which has an ionization constant of ~ 10^-4. 2  im pretty sure C and D are both out because they are both acids. a) calcium nitrate. ( 3 C) cuz Na will act with water and form NaOH. Janice Â· 1 year ago.
