Chemistry 102: Acids: Choose one or more salts that produces a basic solution in water, and write the reaction responsible for being basic.

Question

15.

part 1) Which of the following salts produces a basic solution in water: NaF, KCl, NH₄Cl? Choose all that apply.

Choose one or more:

NaF

KCl

NH₄Cl

None of the choices will form a basic solution.

part 2) Write the reaction responsible for the solution being basic. Spectator ions do not need to be included.

Answer 1

To find basic salts, look at the anion and see if it forms a weak acid. It it does, than it will form that acid and take H⁺ out of the water and make the solution more basic. (The strong acids are nitric, sulfuric, hydrochloric, hydroiodic, hydrobromic, perchloric) . HF is a weak acid.

F^-+ H₃O⁺ → HF + OH^- (as you can see OH^- is liberated)
