Reactions in Aqueous Solution What does it mean to dissolve (aq)? Solute, solvent, solution
Nonelectrolytes Dissolve without breaking into pieces No charged particles, so the solution does not conduct electricity Molecular compounds
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
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
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
