1. Net Ionic Equations Review Grade lab reports Notes on Net ionic equations Guided Practice Homework

2. Write, predict, balance 1. Sulfur dioxide reacts with water.

3. Date: Net Ionic Equations

4. Electrolytes Many times the reactants of DR rxns are in aqueous solutions. This means that the compound (ionic salt) actually separates into its cation and anion in water They become electrolytes. Able to conduct electricity Observe: strong, weak and non-electrolytes

5. All important product, AIP In order for a double replacement reaction to occur, it must create: precipitate(solid) water gas

6. Example Problem AgNO 3 + NaCl  AgCl + NaNO 3 Using the solubility chart, determine the state of matter of each compound. This is the MOLECULAR EQUATION Which is the all important product?

7. Which cation and anion came together to form AIP? Ag + (aq) + Cl - (aq)  AgCl (s) What’s scratched are called spectator ions!

8. BaCl 2 + MgSO 4  MgCl 2 + BaSO 4 Ba +2 (aq) + SO 4 -2 (aq)  BaSO 4(s)

9. Sr(C 2 H 3 O 2 ) 2 +Na 2 SO 4  SrSO 4 + 2NaC 2 H 3 O 2 Sr +2 (aq) + SO 4 -2 (aq)  SrSO 4(s)
