K3PO4 is a white powder at room temperature. It is soluble in water. Its melting point is 1380 ̊C (2516 ̊F), density 2.564 g/cm3. K3PO4 can be used as fertilizer or food additive.
Example Reactions:
• 3KOH + H3PO4 = K3PO4 + 3H2O
• Na3PO4 + 3KOH = 3NaOH + K3PO4
• 3AgNO3 + K3PO4 = 3KNO3 + Ag3PO4↓
• K3PO4 + 3HCl = 3KCl + H3PO4
• 2KOH + KH2PO4 = K3PO4 + 2H2O
• K3PO4 + Al(NO3)3 = AlPO4↓ + 3KNO3
• 3KNO3 + Na3PO4 = K3PO4 + 3NaNO3
• AlCl3 + K3PO4 = 3KCl + AlPO4↓
• 3KI + Na3PO4 = 3NaI + K3PO4
• Cr(NO3)3 + K3PO4 = 3KNO3 + CrPO4↓
