Why standardize the primary standard when preparing a titration?
To test the purity of the reagent being used in the titration.
To ensure that the endpoint indicator matches the expected color change in the titration.
To adjust the pH to match that of the standard titrant solution.
To accurately determine the concentration of the titrant solution.

Excess hydroxide ion from NaOH and water.
The sodium ion from NaOH and water.
Dissociated hydrogen ions from the weak acid and water.
