Unformatted text preview: Solution Reactions Chemical reactions in solution can be written in three different forms: Molecular Equation Gives the overall reaction stoichiometry but not necessarily the actual form of the reactants and products in solution. For example, when you mix HCl with aqueous NaOH, a reaction occurs that forms water and the salt NaCl. HCl (aq) + NaOH (aq) H 2 O (aq) + NaCl (aq) This is a molecular equation. It doesn't give a clear picture of what actually occurs in solution. Each reactant and product, HCl (aq) , NaOH (aq) , H 2 O (aq) , and NaCl (aq) , actually exist in solution split into their respective cations and anions. Complete Ionic Equation Represents all solution phase reactants and products that are strong electrolytes as ions. H + (aq) + Cl- (aq) + Na + (aq) + OH- (aq) H 2 O (aq) + Na + (aq) + Cl- (aq) This is a more accurate representation of what actually exists in the solution than the molecular equation shown...
