  1. Warm Up #1 • What are the charges of the following: Na and PO4 Iron (III) and Chlorine • What are the compounds when they bond together? • Predict the products when Na and PO4 combine with Iron(III) and chlorine. What type of reaction is this?

  2. Chapter 11.3: Solubility

  3. Review • Solubility – ability for something to be dissolved • If soluble: label it (aq) – aqueous • Precipitate – solid that forms from an insoluble reaction • If insoluble: label it (s) - solid

  4. Example • Example: Na3PO4(aq) + FeCl3(aq)  FePO4(s) + NaCl(aq) • Sodium Chloride (NaCl) = soluble (aq) • Iron (III) Phosphate (FePO4) = precipitate (s)

  5. Predicting Solubility Insoluble Stuff: • Ions: most things with Pb+2, Ag+1, Hg+2, Ba+2, Sr+2, Ca+2 • Polyatomics: most Carbonates, Phosphates, Chromates, Oxides and Hydroxides • Everything else = SOLUBLE

  6. Solubility Chart • This will be on your test:

  7. No Reactions… • If two solutions react together and BOTH products = precipitates…NO REACTION • Ex. FeSO4(aq) + Ba(OH)2(aq)  BaSO4(s) + Fe(OH)2(s) • BOTH are insoluble…therefore there is NO reaction.

  8. Ionic Equations • Ex. Na2CO3(aq) + Ba(NO3)2(aq)  BaCO3(s) + NaNO3(aq) • Ionic Equations – show how these reactions occur • Ions = aqueous (except Pb) – dissolved in water • Precipitates = solid • Complete Ionic Equation: Na+1(aq) + CO3-2(aq) + Ba+2(aq) + NO3-1(aq)  BaCO3(s) + Na+1(aq) + NO3-1(aq)

  9. Net Ionic Equation • Spectator Ions – ions that dissolve completely, DO NOT make precipitates • Na+1 and NO3-1 • Net Ionic Equation – JUST showing precipitation reaction (BaCO3) • Complete: Na+1(aq) + CO3-2(aq) + Ba+2(aq) + NO3-1(aq)  BaCO3(s) + Na+1(aq) + NO3-1(aq) • Net Equation: Ba+2(aq) + CO3-2(aq)  BaCO3(s)

  10. Warm Up #5 For the following reactions, predict the products, balance the equation and write complete/net ionic equations (labeling states of matter) • __Pb(NO3)2(aq)+ __NaCl(aq)  • Aqueous solutions of Potassium hydroxide + Iron (III) Sulfate are mixed.
