CHEM 121 Chapter Notes - Chapter 7: Noble Gas, Oxidation State, Oxidizing Agent
Document Summary
Terms: (aq) + cl (aq) (electric current) Electrolytes (dissolve in water to produce conducting solutions of ions) Nonelectrolytes (do not produce ions in aqueous solutions) Strong electrolytes (compounds that dissociate large extent (70-100%) into ions when dissolved in water) Weak electrolytes (compounds that dissociate to only small extent) Many common chemical reactions that take place in aqueous solution fall into one of 3 general categories: Precipitation reactions (processes in which soluble ionic reactants yield an insoluble solid product called precipitate, which falls out of solution thereby removing some of dissolved ions) *ex: pb(no3)2 (aq) + 2 ki(aq) --> 2 kno3 (aq) + pbi2 (s) Acid-base neutralization reactions (processes in which an acid reacts with base to yield water plus an ionic compound called salt) *ex: hcl(aq) + naoh(aq) --> h2o(l) + nacl(aq) Oxidation-reduction reactions (redox reactions) (processes in which one or more electrons are transferred between reaction partners (atoms, molecules, ions))
