Lessons

  1. 1Characteristics of SolutionsThe vocabulary of solutions (solute, solvent, saturation) and how to tell electrolytes from non-electrolytes by conductivity.12 questions
  2. 2How Dissolving HappensThe particle-level mechanism of dissolving for ionic vs. molecular compounds, the 'like dissolves like' rule, and dissociation vs. ionization.11 questions
  3. 3Solubility CurvesReading solubility curves to determine saturation state, and the opposite temperature trends for solids vs. gases.Interactive11 questions
  4. 4ConcentrationMeasuring how much solute is packed into a solution: molar concentration, g/L, ppm, percent concentration, and preparing standard solutions.11 questions
  5. 5DilutionsWhy C1V1 = C2V2 works (moles of solute are conserved) and correct dilution technique.11 questions
  6. 6Ions in Solution & Precipitation ReactionsWriting formula, total ionic, and net ionic equations for precipitation reactions using solubility rules to predict spectator ions.11 questions
  7. 7Qualitative Analysis: Identifying Unknown IonsUsing selective precipitation and flame tests to identify which ions are present in an unknown solution.11 questions
  8. 8Solution StoichiometryStoichiometry calculations where quantities are given as concentration and volume instead of mass, including limiting reagent problems between two solutions.11 questions
  9. 9Properties & Naming of Acids and BasesGeneral physical/chemical properties of acids and bases, and the naming rules for binary acids, oxyacids, and metal hydroxide bases.11 questions
  10. 10Arrhenius Theory of Acids and BasesArrhenius definitions of acids/bases, dissociation vs. ionization in the acid/base context, and strong vs. weak (not the same as concentrated vs. dilute).10 questions
  11. 11The pH ScalepH and pOH, the relationship pH + pOH = 14, and converting between [H+] and pH in both directions.11 questions
  12. 12TitrationNeutralization reactions, titration technique, equivalence point vs. endpoint, indicators, and calculating unknown concentrations from titration data.Interactive11 questions
