Cyanides are weak bases when dissolved in water pKb=4.8
Barium Sulfate (BaSO4) is neither an acid nor a base it is a salt
It is a base
Barium hydroxide, Ba(OH)2, is a base.
Barium Cyanide
Barium fluoride can be considered to be the salt of barium hydroxide (a weak base) and HF (a strong acid). And a solution of BaF2 will be weakly acidic.
