Unformatted text preview: s compounds; break up strong electrolytes 3. Cancel spectator ions 4. Simplify coefficients if possible 5. If all reactants and products cancel (all spectator ions) NR Experimental Observations of Double‐ Replacement Precipitation and Acid‐Base Neutralization Reactions – Given a table of experimental results similar to the “Double Replacement/Metathesis” experiment, determine the cation and anion that must be present in a solution of an unknown soluble ionic compound Oxidation‐Reduction (Redox) Reactions – Be able to determine oxidation numbers for all the atoms/elements in a chemical equation. – Use oxidation numbers to determine which reactant was oxidized (reducing agent) and which reactant was reduced (oxidizing agent) – Determine the # of electrons gained or lost. Balance redox reactions in acidic and basic solution using the half‐reaction method. – Balance atoms and electrons transferred, then balance O atoms using H2O and H atoms using H+ ions (in acidic solution) – In basic solution, neutralize H+ ions with OH‐ ions – Cancel H+, OH‐, and H2O on both sides of the equation and simplify coefficients Molarity, Solution Stoichiometry, and Volumetric An...
