Weak Acids (16.2.3)

Question 1

• The acid-dissociation constant (Ka) is the equilibrium constant for the partial dissociation of a weak acid in aqueous solution.

Answer 1

• The acid-dissociation constant (Ka) is the equilibrium constant for the partial dissociation of a weak acid in aqueous solution.

Question 2

• Ka values can be used to calculate equilibrium concentrations of H+ in acid solutions.

Answer 2

• Ka values can be used to calculate equilibrium concentrations of H+ in acid solutions.

Question 3

• For a weak acid, percent dissociation is less than 100% and depends on the initial concentration of HA.

Answer 3

• For a weak acid, percent dissociation is less than 100% and depends on the initial concentration of HA.
