H+(aq)+F−(aq)⇌HF(aq)cap H raised to the positive power open paren a q close paren plus cap F raised to the negative power open paren a q close paren is in equilibrium with cap H cap F open paren a q close paren to the right. This decreases , causing the CaF2cap C a cap F sub 2 solubility equilibrium to shift right to replenish F−cap F raised to the negative power , thereby .
