E340 Potassium Orthophosphates

Potassium orthophosphates (Potassium phosphates, potassium phosphate, monopotassium phosphate, dipotassium phosphate, tripotassium phosphate, potassium orthophosphate, single-substituted potassium orthophosphate, double-substituted potassium orthophosphate, tri-substituted potassium orthophosphate, potassium tripolyphosphate, potassium phosphate, E340) are potassium salts of orthophosphoric acid.

Types of potassium orthophosphates (potassium phosphates):

• (i) Single-substituted potassium orthophosphate (monopotassium phosphate, KH₂PO₄);
• (ii) Potassium orthophosphate, dipotassium phosphate, K₂HPO₄);
• (iii) Tri-substituted potassium orthophosphate (tripotassium phosphate, K₃PO₄).
