Potassium Dihydrogen Phosphate (KH2PO4), also known as Monopotassium Phosphate (MKP), is a compound valued for its chemical stability, solubility, and diverse functionalities. For professionals in chemical procurement, R&D, and manufacturing, understanding its properties and safety guidelines is crucial. As a dedicated chemical supplier, we provide essential information about KH2PO4 to ensure informed decision-making and safe handling.

Chemical Structure and Properties:

Potassium Dihydrogen Phosphate is an inorganic salt with the molecular formula KH2PO4. It is formed from the reaction of phosphoric acid with potassium carbonate or hydroxide. Key properties include:

  • Appearance: Typically a white crystalline powder or granules.
  • Solubility: Highly soluble in water, with limited solubility in alcohol. Its aqueous solutions are acidic, with a pH of around 4.4-4.8 for a 1% solution.
  • Molecular Weight: Approximately 136.09 g/mol.
  • Melting Point: Decomposes around 253 °C (487 °F), but it's often cited with a melting point of 252.6 °C.
  • Hygroscopic Nature: It can absorb moisture from the air, so proper storage is important.
  • Buffering Capacity: Acts as an effective buffering agent in solution, helping to maintain a stable pH.

Applications Driven by Properties:

These properties enable KH2PO4 to be used across various industries:

  • Agriculture: As a source of readily available phosphorus and potassium for plants.
  • Food Industry: As a buffer, leavening agent, and nutrient fortifier.
  • Industrial Processes: In optical applications due to its non-linear optical properties, and as a component in chemical synthesis.

Safety and Handling Guidelines:

While Potassium Dihydrogen Phosphate is generally considered safe for its intended uses when handled properly, it's important to adhere to standard chemical safety practices:

  • Personal Protective Equipment (PPE): Wear appropriate PPE, including gloves, safety glasses, and lab coats, when handling the chemical to prevent skin and eye contact.
  • Ventilation: Handle in a well-ventilated area to avoid inhaling dust.
  • Storage: Store in a cool, dry place in tightly sealed containers to prevent moisture absorption. Keep away from incompatible materials.
  • Incompatibilities: Avoid contact with strong bases and oxidizing agents.
  • Disposal: Dispose of waste materials according to local regulations.
