Acid Base Titration

An acid-base titration is the method of quantitative analysis for determining the concentration of an acid and base by exactly neutralizing it with a standard solution of base or acid having known concentration.

Question

Given:

Mg(OH)₂ _(s) <--> Mg²⁺_(aq) + 2 OH^- _(aq) K_c = 5.60 x 10^-12

F^- _(aq) + H₂O _(l) <--> HF _(aq) + OH^- _(aq) K_c = 1.47 x 10^-11

Calculate Kc for the following ( Change equations above so they sum to the equation below).

Mg(OH)₂ _(s) + 2HF_(aq) <--> Mg²⁺_(aq) + 2F^- _(aq) + 2H₂O _(l) K_c = ?
