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.✓ Correct
thermodynamically favorable, because K3 > 1
C.
not thermodynamically favorable, because K1 < 1
D.
not thermodynamically favorable, because K3 < 1
