question 56

Multiple Choice

Consider the equilibrium of magnesium fluoride,MgF₂(s) ,in water. MgF₂(s) ? Mg²⁺(aq) + 2F?(aq) , What is the effect of adding perchloric acid (i.e.decreasing the pH of solution) ?

• A) The acid will have no effect on the magnesium fluoride equilibrium.
• B) The F? will be protonated,resulting in more MgF₂(s)dissolving.
• C) More MgF₂(s)will be formed,thus reducing Mg²⁺ and F? concentrations in solution.
• D) Magnesium perchlorate,Mg(ClO₄)₂(s),will precipitate.
• E) Magnesium hydride,MgH₂(s),will precipitate.
