Understanding Types of Equations for Aqueous Reactions in Chemistry

This tutorial explains the three primary types of equations for reactions in aqueous solutions: molecular, complete ionic, and net ionic equations. Molecular equations provide a simplified overview of the reaction, while complete ionic equations illustrate all strong electrolytes as ions. Net ionic equations focus on the components that undergo change, omitting the spectator ions. Examples include the reaction of sodium chloride with silver nitrate and potassium hydroxide with iron(III) nitrate, highlighting how to write each type of equation appropriately.

  1. Writing Equations for Reactions in Solution Nia Gilliam 5/6 periods Chem. II, 3rd tutorial

  2. Types of Equations for Reactions in Aqueous Solutions 3 types: Molecular-shows overall reaction but not all forms of reactants and products in solution Complete ionic-represents all reactants and products that are strong electrolytes as ions. Net ionic-includes only the components that undergo a change, not spectator ions.

  3. Aqueous sodium chloride is added to aqueous silver nitrate yields to make solid silver chloride and aqueous sodium nitrate.Complete ionic equation: Na+(aq)+Cl-(aq)+Ag+(aq)+NO3-(aq)AgCl(s)+Na+(aq)+NO3-(aq)

  4. Aqueous sodium chloride is added to aqueous silver nitrate yields to make solid silver chloride and aqueous sodium nitrate.Molecular equation: NaCl(aq)+AgNO3(aq) AgCl(s)+NaNO3(aq)

  5. Aqueous sodium chloride is added to aqueous silver nitrate yields to make solid silver chloride and aqueous sodium nitrate.Net ionic equation: CL-(aq)+Ag+(aq)AgCl(s)

  6. Aqueous potassium hydroxide is mixed with aqueous iron(III) nitrate yields to make solid iron(III) hydroxide plus aqueous potassium nitrate.Molecular equation: 3KOH(aq)+Fe(NO3)3(aq) Fe(OH)3(s)+3K+(aq)+3NO3-(aq)

  7. Aqueous potassium hydroxide is mixed with aqueous iron(III) nitrate yields to make solid iron(III) hydroxide plus aqueous potassium nitrate.Complete ionic equation: 3K+(aq)+3OH-(aq)+Fe3+(aq)+ 3NO3-(aq) Fe(OH)3(s)+3K+(aq)+ 3NO3-(aq)

  8. Aqueous potassium hydroxide is mixed with aqueous iron(III) nitrate yields to make solid iron(III) hydroxide plus aqueous potassium nitrate.Net ionic equation: 3OH-(aq)+ Fe3+(aq)Fe(OH)3(s)
