CaCO3 is a white powder at room temperature. It is soluble in water. Its melting point is 1339 ̊C (2442.2 ̊F). CaCO3 is widely used in building industry such as making cement, paint wall. It's also the main component of chalk used for blackboard in the old times.
Example Reactions:
• 2HCl + CaCO3 = CaCl2 + CO2 + H2O
• Ca(OH)2 + CO2 = CaCO3↓ + H2O
• CaCO3 + H2SO4 = CaSO4 + CO2 + H2O
• Ca(NO3)2 + Na2CO3 = 2NaNO3 + CaCO3↓
• Na2CO3 + CaCl2 = CaCO3↓ + 2NaCl
• CaCO3 + 2HCl = CaCl2 + H2CO3
• CaCO3 + 2HNO3 = Ca(NO3)2 + CO2 + H2O
• CaCl2 + (NH4)2CO3 = 2NH4Cl + CaCO3↓
• Ca(OH)2 + Na2CO3 = 2NaOH + CaCO3↓
• CaCl2 + 2NaHCO3 = 2NaCl + CaCO3↓ + CO2 + H2O
