What is the Difference Between KH2PO4 and K2HPO4?

🆚 Go to Comparative Table 🆚

The main difference between KH2PO4 and K2HPO4 is the number of hydrogen ions or protons they can take up and the amount of potassium they release when used in fertilizers.

  • KH2PO4: This compound is monobasic, meaning it can take up only one hydrogen ion or proton from its solution. It can release a low amount of potassium when used in fertilizers.
  • K2HPO4: This compound is dibasic, meaning it can take up to two hydrogen ions or protons from its solution. It can release a high amount of potassium when used in fertilizers.

In summary, KH2PO4 is a monobasic compound that releases a low amount of potassium, while K2HPO4 is a dibasic compound that releases a high amount of potassium when used in fertilizers.

    • Comparative Table: KH2PO4 vs K2HPO4

    The main difference between KH2PO4 and K2HPO4 is their monobasic and dibasic properties, which refers to the number of potassium cations bound to the phosphate. KH2PO4 is a monobasic compound, meaning it can release a low amount of potassium, while K2HPO4 is a dibasic compound, meaning it can release a high amount of potassium when used in fertilizer. Monobasic compounds can take up only one hydrogen ion or proton, whereas dibasic compounds can take up to two hydrogen ions or protons. Here is a comparison table of the two compounds:

    Property KH2PO4 (Potassium Dihydrogen Phosphate) K2HPO4 (Potassium Hydrogen Phosphate)
    Monobasic or Dibasic Monobasic Dibasic
    Potassium Release Low amount of potassium released High amount of potassium released
    Hydrogen Ion/Proton Absorption Can take up only one hydrogen ion or proton Can take up to two hydrogen ions or protons
    Fertilizer Application Suitable for use in fertilizers Suitable for use in fertilizers
    pH Adjustment Can affect the pH of solutions Can affect the pH of solutions

    Both KH2PO4 and K2HPO4 can be used in fertilizers, and they can affect the pH of solutions they are dissolved in. The choice between KH2PO4 and K2HPO4 in a specific application, such as MOPS media or fertilizer, depends on the desired potassium release and pH adjustment requirements.
