Na2CO3 + CaCl2 = NaCl + CaCO3 is a Double Displacement (Metathesis) reaction where one mole of aqueous Sodium Carbonate [Na2CO3] and one mole of aqueous Calcium Chloride [CaCl2] react to form two moles of aqueous Sodium Chloride [NaCl] and one mole of solid Calcium Carbonate [CaCO3]For...
2NaCl(aq)→2Na+(aq)+2Cl-(aq) 2Na+(aq)+ CO32-(aq)+ Fe2+(aq)+2Cl-(aq)=2Na+(aq)+2Cl-(aq)+ FeCO3(s) Spectator Ions Spectator ions are ions that do not take part in the reaction. They are removed from the complete ionic equation to get the net ionic equation. ...
Calcium carbonate (CaCO3) was synthesized in the CaCl2-Na2CO3-H2O reaction system at the reaction temperature of 40, 50, 60, and 70℃. The initial pH was changed to 2.4-11.0 at 50-70℃. The initial pH was adjusted by changing the pH of CaCl2 aqueous solution using HCl and NH3 aqueous...
