Applications of Potassium Hydrogen Phthalate:

• Titration Standard: Potassium Hydrogen Phthalate is primarily used as a primary standard in acid-base titrations. It is used to standardize sodium hydroxide (NaOH) solutions because it has a known and stable composition.
• pH Calibration: It can be used for calibration in the preparation of buffer solutions.
• Analytical Chemistry: Useful for other calibration purposes in volumetric analysis.

Advantages of Potassium Hydrogen Phthalate as a Primary Standard:

• It is stable and non-hygroscopic, so it can be weighed accurately without absorbing moisture from the air.
• It has a known, precise molecular weight, which makes it excellent for accurate titration and standardization.
