Which statement below is true about an aqueous solution of potassium fluoride, KF, and why?
A) An aqueous solution of KF has a pH value that is greater than 7.0 because fluoride, F - , reacts with water to produce more OH - .
B) An aqueous solution of KF has a pH value that is greater than 7.0 because fluoride, F - , reacts with water to produce more H3O+.
C) An aqueous solution of KF has a pH value that is less than 7.0 because fluoride, F - , reacts with water to produce more OH - .
D) An aqueous solution of KF has a pH value that is less than 7.0 because fluoride, F - , reacts with water to produce more H3O+.
E) An aqueous solution of KF has a pH value that is equal to 7.0 because neither the potassium ion or the fluoride ion reacts with water to produce H3O+ or OH - .
