question 170

Multiple Choice

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 ^- .
