Unformatted text preview: They do not dissociate into ions Net Ionic Equation: Net •From the ionic equation, cancel out any species that appear on either side of the equation. •These are known as the “spectator ions” and they are never part of a net ionic equation! Writing Net Ionic Equations Molecular Equation: Pb(NO3)2(aq) + 2KI(aq) → 2KNO3(aq) + PbI2(s) Writing Net Ionic Equations Molecular Equation: Pb(NO3)2(aq) + 2KI(aq) → 2KNO3(aq) + PbI2(s) Total Ionic Equation: Pb2+ (aq) + 2NO3– (aq) + 2K+(aq) + 2I–(aq) → Never break up Never any (s), (l) or (g) or molecular (aq) species! (aq) 2K+(aq) + 2NO3– (aq) + PbI2(s) Acids & Bases Arrhenius Definition: Arrhenius • An acid is any substance that increases the H+(aq) concentration in an aqueous solution. HX(aq) → H+(aq) + X–(aq) • A base is any substance that increases the base OH–(aq) concentration in an aqueous solution. MOH(aq) → M+(aq) + OH–(aq) Acids and Bases Brönsted-Lowry: Br • An acid is any substance that donates H+(aq) to another spec...
