Chemical Properties

Monopotassium phosphate (MKP) is a compound noted for its composition of potassium and phosphate ions. It exhibits unique physical characteristics and is known for its solubility and stability in water.

Composition and Structure

Monopotassium phosphate (E340) is chemically represented as KH₂PO₄. It consists of one potassium ion (K⁺) and one dihydrogen phosphate ion (H₂PO₄⁻).

The crystal structure of MKP is orthorhombic, with several polymorphs based on temperature.

Each molecule binds through ionic bonds, contributing to its stability.

The molecular weight is 136.09 g/mol, indicating a relatively lightweight compound.

Key Elements:

Potassium (K): Essential for plant growth.
Phosphate (H₂PO₄⁻): Provides phosphorus, another vital nutrient.

Physical Characteristics

Monopotassium phosphate appears as a colorless or white crystalline powder. Its density is approximately 2.338 g/cm³.

When heated, MKP transitions to a glassy phase around 252°C.

MKP has a melting point at high temperatures, but before reaching the melting point, it decomposes without boiling.

It’s notable for its non-flammable and non-combustible properties, making it safe for various applications.

Solubility and Stability

Monopotassium phosphate is highly soluble in water, with a solubility of 22g/100mL at 25°C.

This high solubility allows for easy dissolution in aqueous solutions, which is particularly beneficial for agricultural and industrial uses.

It remains stable under normal environmental conditions, resisting oxidation and reduction.

In strong acidic or basic environments, MKP may hydrolyze, but it generally maintains its integrity.
