Question

The following are representations of the initial concentrations of a weak acid HA (pKa = 6.15) and its potassium salt KA. Draw a representation of the equilibrium state of solution (4) upon the addition of 1 OH⁻ ion. (The potassium ions and water molecules were omitted for clarity).

Initial concentrations of weak acid HA and its salt KA in solution.

Accepted Answer

Representation of weak acid HA in solution before OH- addition.

Answer

Representation of weak acid HA in solution after adding 1 OH- ion.

Answer

Representation of weak acid HA in solution after further OH- addition.

Answer

Final representation of weak acid HA in solution after multiple OH- additions.
