1. Equation Writing
Target--Students should be able to determine the product in a precipitation reaction based upon solubility rules and write the equation for the reaction using molecular, complete ionic and net ionic equation formats.

2. Describing Reactions in Solution
1.Molecular equation (reactants and products as compounds)
AgNO3(aq) + NaCl(aq)  AgCl(s) + NaNO3(aq)
2.Complete ionic equation (all strong electrolytes shown as ions)
Ag+(aq) + NO3(aq) + Na+(aq) + Cl(aq) 
AgCl(s) + Na+(aq) + NO3(aq)

3. Describing Reactions in Solution (continued)
3. Net ionic equation (show only components that actually react)
Ag+(aq) + Cl(aq)  AgCl(s)
Na+ and NO3 are spectator ions.
