• Monopotassium phosphate (KH₂PO₄)
• Dipotassium phosphate (K₂HPO₄)
• Tripotassium phosphate (K₃PO₄)

As food additives, potassium phosphates have the E number E340.

The ratio of potassium to phosphate in K-Phos solution is 4.3:3 (K:PO₄). The ratio of potassium to phosphate in K-Phos Neutral packets for oral administration is 1:1, 14.25 mEq potassium and 14.25 mmol phosphate per packet.
