  1. Reaction in Aqueous Solutions

  2. Aqueous Solutions Is a solution where Your reactant is dissolved in water (solute) And the water is the solvent

  3. Why is this important Water pulls the ionic compound, or some covalent molecules apart because of its polarity This means that if you dissolve a substance in water it is actually the charged particles floating independently. HCl H1+ + Cl1- This means that the ions are more able to react with each other.

  4. Ionic Equations • 2Na1+(aq) + 2OH1-(aq) + Cu2+(aq) + 2Cl1-(aq) • 2Na1+(aq) + 2Cl1-(aq) + Cu(OH)2 (s) • Complete Ionic Equations • Shows everything in aqueous solution as it’s charged form. • Spectator ions are not shown in equations. So H2O is not usually shown, or if something doesn’t form a solid and stays in aq it will also be a spectator ion • Net Ionic- is the equation removing any spectator ions

  5. Net ionic equation 2OH- + Cu2+ Cu(OH)2 Write out the following problems in ionic and then net ionic form HCl(aq) + NaOH(aq) NaCl(s) + H2O(l) CuSO4(aq) + Fe(s)  FeSO4(aq) + Cu(s)

  6. What does it form Aqueous solutions can form all 4 states of matter. Forming a solid If a reactions has a solid falling out of solution it makes a precipitate An aqueous solution of potassium iodide and silver nitrate are mixed. Silver iodide precipitates out of solution

  7. Reactions that make water Chemical reactions that form water may be the hardest to visualize as chemical reaction has formed. If your reactants are already mixed in water not much will change if you make more water. When you made salt in lab you had to boil your reaction why?

  8. Reactions that form gases HI(aq) + Li2S (aq) H2S(g) + 2LiI(aq) Write that as a ionic equation. What is the net ionic equation? You are more able to form a gas in an aqueous solution than if you are going from a solid because the ions are separated out.

  9. Work on your own • Practice problem • P302 problems 37 and 38 • P 304 problems 40 and 42 • P 306 problems 45 and 46
