Total Ionic Equation: When you write the dissociated form of the ionic compounds dissolved in water you have the total ionic equations.
Net Ionic Equation: During a double displacement reaction if one of the products formed is a compound with low solubility, which can be determined from the solubility rules; we say we have a precipitate. Writing the formation of the precipitate or the solid product formed from its constituent ions is called net ionic equations.
Spectator Ions: The ions present in solution after a double displacement reaction, they do not precipitate. Hence they are called spectator ions. We strike through the spectator ions in the total ionic equation.
As a prelude start writing the dissociation products of the following ionic compounds and identify the compounds with low solubility.
Sodium Phosphate
Barium Nitrate
Potassium Sulfate
Sodium Chromate
Strontium Sulfate
Sulfuric Acid
Lead Iodide
Ammonium Sulfate
Ammonium Nitrate
Silver Chloride
Silver Nitrate
Calcium Chloride
Total Ionic Equation
Pb(NO3)2(aq) + 2KI(aq) $latex \rightarrow$ PbI2(s) + 2KNO3(aq)
Pb2+ (aq) + 2NO3– (aq) + 2K+ (aq) + 2I–(aq) $latex \rightarrow$ PbI2(s) + 2K+ (aq) + 2NO3– (aq)
Net ionic equation is written for the solid precipitate formed
Net Ionic Equations:
Pb(NO3)2(aq) + 2KI(aq) $latex \rightarrow$ PbI2(s) + 2KNO3(aq)
Pb2+ (aq) + 2NO3–(aq) + 2K1+(aq) + 2I–(aq) $latex \rightarrow$ PbI2(s) + 2K1+(aq) + 2NO3–(aq)
Pb2+ (aq) + 2I–(aq) $latex \rightarrow$ PbI2(s)
Total and Net Ionic Equation
Predict the solubility of the compounds formed in aqueous solution and write the total ionic equations and the net ionic equations for the following reaction
Identify the spectator ions in the following double displacement reactions – Use solubility rules if needed.
Barium Chloride + Potassium Sulfate $latex \rightarrow$ Barium Sulfate + Potassium Chloride
Calcium Chloride + Sodium Sulfate $latex \rightarrow$ Calcium Sulfate + Sodium Chloride
Barium Nitrate + Sodium Chromate $latex \rightarrow$ Barium Chromate + Sodium Nitrate
Lead(II) Nitrate + Potassium Chloride $latex \rightarrow$
Lead(II) Acetate + Hydrochloric acid $latex \rightarrow$
