FeF2(s) ⇄ Fe2+(aq) + 2 F−(aq) K1 = 2 × 10−6 F−(aq) + H+(aq) ⇄ HF(aq) K2 = 1 × 103 FeF2(s) + 2 H+(aq)Equilibrium Chemistry Question

Question

FeF2(s) ⇄ Fe2+(aq) + 2 F−(aq) K1 = 2 × 10−6
F−(aq) + H+(aq) ⇄ HF(aq) K2 = 1 × 103
FeF2(s) + 2 H+(aq) ⇄ Fe2+(aq) + 2 HF(aq) K3 = ?

On the basis of the information above, the dissolution of FeF2(s) in acidic solution is

A.

thermodynamically favorable, because K2 > 1

B.

thermodynamically favorable, because K3 > 1

✓ Correct
C.

not thermodynamically favorable, because K1 < 1

D.

not thermodynamically favorable, because K3 < 1
