Chemical Properties: Mg H2po3 2 Chemical Name
Magnesium hydrogen phosphate dihydrate (MgH 2PO 3·2H 2O) exhibits both acidic and basic properties due to its amphoteric nature.
Acidity and Basicity
MgH 2PO 3·2H 2O reacts with both acids and bases, demonstrating its amphoteric nature. When it reacts with a strong acid like hydrochloric acid (HCl), it acts as a base and forms magnesium chloride (MgCl 2) and phosphoric acid (H 3PO 4):
MgH2PO 3·2H 2O + 2HCl → MgCl 2+ H 3PO 4+ 2H 2O
Conversely, when MgH 2PO 3·2H 2O reacts with a strong base like sodium hydroxide (NaOH), it acts as an acid and forms magnesium sodium phosphate (MgNaPO 3) and water (H 2O):
MgH2PO 3·2H 2O + NaOH → MgNaPO 3+ 3H 2O
Reactions with Other Chemicals
MgH 2PO 3·2H 2O reacts with various other chemicals. For example, it reacts with silver nitrate (AgNO 3) to form a white precipitate of silver phosphate (Ag 3PO 4) and magnesium nitrate (Mg(NO 3) 2):
3MgH2PO 3·2H 2O + 6AgNO 3→ Ag 3PO 4+ 2Mg(NO 3) 2+ 6H 2O
Thermal Stability
MgH 2PO 3·2H 2O is thermally stable up to approximately 100°C. Upon heating beyond this temperature, it undergoes dehydration and decomposition to form magnesium pyrophosphate (Mg 2P 2O 7) and water:
2MgH2PO 3·2H 2O → Mg 2P 2O 7+ 4H 2O
