Lecture 12, Precipitation Reactions

Precipitation Reactions

1. Dissolving and Ionic Solid
   1. Video (CD-ROM Internet)
   2. Animation (CD-ROM Internet)

2. Solubility Rules

3. Demo (silver nitrate and sodium chloride)

4. Equations for Demo

   Dissociation

   AgNO₃ (s) - > Ag¹⁺ (aq) + NO₃^1- (aq)
   NaCl s)- > Na¹⁺ (aq) + Cl^1- (aq)

   Balanced overall eqaution

   AgNO₃ (aq) + NaCl aq) - > AgCl (s) + NaNO₃ (aq)

   Total Ionic Equation

   Ag¹⁺ (aq) + NO₃^1- (aq) + Na¹⁺ (aq) + Cl^1- (aq) -> AgCl (s) + Na¹⁺ (aq) + NO₃^1- (aq)

   Net Ionic Equation

   Ag¹⁺ (aq) + Cl^1- (aq) -> AgCl (s)

5. Identifying the Precipitate

6. Example
