Question

Which of the following substances will affect the solubility of BaF2 in aqueous solution? Select ALL that apply.

a. LiF

b. H₂SO₄

c. NaOH

_{d. BaCl2}

e. KNO₃

Answer 1

Answer #1

LiF and BaCl2 will surely effect the solubility of BaF2 due to common ion effect.
LiF has common ion F- same as BaF2 and BaCl2 has common ion Ba2+.

BaF2 is salt of Strong base (Ba(OH)2) and weak acid
Only base is strong
So, the salt BaF2 is basic

Since BaF2 is basic salt, the addition of acid and base will also effect the solubility.

So, NaOH and H2SO4 will effect the solubility of BaF2

Answer: a, b, c, d
