CHE-1101 Lecture Notes - Lecture 17: Sulfuric Acid, Nonmetal, Sodium Chloride
Document Summary
When ions are present in solution, the solution can conduct electricity. The conductivity of the solution increases with the increasing concentration. Test covers chapter 7, 3 and a little of 4. Will have some equations given (light, etc. ) Some compounds do not dissociate into ions when dissolved in water. Pb(no3)2(aq) + 2 ki(aq) pbi2(s) + 2 kno3(aq) Pb2+(aq) + 2 no3 - (aq) + 2 k+(aq) + 2 i- (aq) pbi2(s) + 2 k+(aq) + 2 no3 - (aq) Emphasizes compounds that exist as ions in solution. Write the balanced net ionic equation for the reaction that soocurs whrn the solutions of calcium chloride and sodium carbonate are mixed to give a precipitate of calcium carbonate. Ca+ + 2cl- + 2na+ + co2- Svante arrhenius proposed that substances dissociate and produce h + in aqueous solution that should be called acids. Monoprotic acids produce 1 h+ per molecule. Polyprotic acids produce more than 1 h+ per molecule.
