Buy Potassium Acid Phthalate Online

Potassium Acid Phthalate (KHP), also known as Potassium Hydrogen Phthalate, is a crystalline, white, water-soluble solid commonly used as a primary standard in acid-base titrations. With the chemical formula KHC₈H₄O₄, it plays a vital role in analytical chemistry due to its high purity, stability, and precise molar mass.

Whether you are conducting laboratory experiments, calibrating pH meters, or performing standardization of sodium hydroxide (NaOH) solutions, Potassium Acid Phthalate is a trusted choice across industries including pharmaceuticals, education, environmental testing, and chemical manufacturing.

Chemical and Physical Properties of Potassium Acid Phthalate

Understanding the fundamental properties of KHP is essential for anyone working with it in research or production.

These properties make Potassium Acid Phthalate exceptionally reliable as a primary standard for acidimetry and alkalimetry. Its stable and non-hygroscopic nature allows for accurate weighing and long-term storage without significant degradation.

Why Potassium Acid Phthalate Is Used as a Primary Standard

A primary standard is a highly pure chemical used to determine the concentration of solutions in titrations. Potassium Acid Phthalate is one of the most common primary standards due to its outstanding characteristics:

1. High Purity and Stability:
   KHP does not absorb moisture or carbon dioxide from the air easily, ensuring accurate and reproducible results in titrations.

2. Accurate Molecular Weight:
   Its exact molar mass allows for precise calculation of equivalent weight, ensuring dependable concentration determination for standard solutions.

3. Non-Volatile Nature:
   KHP remains stable at room temperature, unlike volatile acids or bases that may lose strength over time.

4. Ease of Handling:
   It is non-toxic and easy to weigh, making it ideal for educational and professional laboratory use.

Because of these advantages, Potassium Acid Phthalate is widely used to standardize sodium hydroxide (NaOH) and hydrochloric acid (HCl) solutions with high precision.

Applications of Potassium Acid Phthalate

Potassium Acid Phthalate is versatile and serves multiple analytical and industrial purposes. Below are the most common applications:

1. Standardization of Bases

KHP is primarily used to standardize strong base solutions, particularly sodium hydroxide (NaOH) and potassium hydroxide (KOH). By titrating a known weight of KHP against these bases, chemists can determine the exact molarity of the base solution with great accuracy.

2. pH Meter Calibration

Buffer solutions made from Potassium Acid Phthalate are used to calibrate pH meters in laboratories. These solutions maintain stable pH values, ensuring precise instrument readings for analytical testing and quality control.

3. Analytical Chemistry Research

In academic and industrial laboratories, KHP serves as a reference material in acid-base titrations, ensuring consistency and accuracy in experimental results. It is also used in the development of analytical reagents and solutions.

4. Quality Control and Environmental Testing

Environmental testing labs use KHP to analyze water samples for acidity and alkalinity. Its reliability makes it an ideal choice for ensuring compliance with environmental safety and purity standards.

5. Education and Laboratory Training

Because it is safe and easy to handle, Potassium Acid Phthalate is a preferred compound for student experiments and laboratory demonstrations involving acid-base chemistry.

How to Use Potassium Acid Phthalate in Titrations

To standardize a sodium hydroxide solution using Potassium Acid Phthalate:

1. Accurately weigh a known amount of KHP (typically around 0.5 g).

2. Dissolve it in distilled water in a clean Erlenmeyer flask.

3. Add 2–3 drops of phenolphthalein as an indicator.

4. Titrate with the sodium hydroxide solution until the faint pink endpoint is reached.

5. Record the titration volume and calculate the molarity of the NaOH solution using KHP’s known molecular weight.

This method ensures highly reliable results and serves as a fundamental experiment in analytical chemistry laboratories.
