Reactions of Calcium Nitrate with Different Substances

Calcium nitrate (Ca(NO3)2) is a compound that can react with various substances. Let's examine the reactions of calcium nitrate with the following substances:

a) Sulfuric acid (H2SO4) b) Phosphorus oxide (P2O3) c) Potassium carbonate (K2CO3) d) Nitric acid (HNO3)

a) Reaction with Sulfuric Acid (H2SO4)

When calcium nitrate reacts with sulfuric acid, it forms calcium sulfate (CaSO4), nitric acid (HNO3), and water (H2O). The balanced chemical equation for this reaction is:

Ca(NO3)2 + H2SO4 → CaSO4 + 2HNO3 + H2O [[1]]

b) Reaction with Phosphorus Oxide (P2O3)

Calcium nitrate reacts with phosphorus oxide to form calcium phosphate (Ca3(PO4)2) and nitric acid (HNO3). The balanced chemical equation for this reaction is:

Ca(NO3)2 + P2O3 → Ca3(PO4)2 + 2HNO3 [[2]]

c) Reaction with Potassium Carbonate (K2CO3)

When calcium nitrate reacts with potassium carbonate, it forms calcium carbonate (CaCO3), potassium nitrate (KNO3), and carbon dioxide (CO2). The balanced chemical equation for this reaction is:

Ca(NO3)2 + K2CO3 → CaCO3 + 2KNO3 + CO2 [[3]]

d) Reaction with Nitric Acid (HNO3)

Calcium nitrate reacts with nitric acid to form calcium nitrate (Ca(NO3)2) and water (H2O). The balanced chemical equation for this reaction is:

Ca(NO3)2 + 2HNO3 → Ca(NO3)2 + 2H2O [[4]]
