1. Reactions in Aqueous Solution What does it mean to dissolve (aq)? Solute, solvent, solution

2. Nonelectrolytes  Dissolve without breaking into pieces  No charged particles, so the solution does not conduct electricity  Molecular compounds

3. Strong electrolytes  Conducts electricity well by splitting into many charged particles  Strong acids and bases are strong electrolytes  Ionic compounds that are very soluble – mostly split apart into ions  KISS rules are used to predict solubility of ionic compounds

4. KISS Rules  #1 Soluble cations: sodium, ammonium, potassium  #2 Soluble anions: nitrate, acetate, chlorate and perchlorate  #3 Mostly soluble anions: chloride, bromide and iodide, soluble except with the silver group (silver, mercury and lead)  #4 Sometimes soluble anion: sulfate, soluble except with the silver group and barium and strontium  #5 Everything else is insoluble

5. Weak electrolytes  Conduct electricity weakly by dissociating only a little bit  Weak acids and bases are weak electrolytes  Ionic compounds that are “insoluble” only dissociate a little bit, and are weak electrolytes
