Unformatted text preview: Writing Chemical Equations for Solutions y Molecular Equation all reactants and products listed as molecules y Complete Ionic Equation all ionic reactants and products separated into ions y Net Ionic Equation ions and molecules that are the same on both sides of the equation are removed Has a reaction occurred? y For a reaction to occur something has to happen 1. Form an insoluble salt 2. Form a gaseous product that escapes 3. Form a weak or non-electrolyte 4. An oxidation-reduction occurs with a transfer of electrons Types of Reactions y Precipitation Reaction form an insoluble solid y Acid-Base Reaction one substance donates a proton and one substance accepts a proton y Gas Evolution Reaction gaseous product forms and escapes y Oxidation-Reduction Reaction a transfer of electrons from one element or ion to another Solubility Rules Precipitation Reaction Precipitation Reaction Predicting Product y FeSO 4 (aq) + KCl (aq) y Al(NO 3 ) 3 (aq) + Ba(OH) 2 (aq) What precipitate if any forms from the...
