1. Unit 14 notes

2. Predicting Solubility
Write the ionic compound
Look up charges
Criss cross

3. Predicting solubility
Use the solubility chart (yellow chart on back of periodic table)
Look up anion (non-metal) on chart
Is it under ‘soluble’ or ‘insoluble’
Are there any acceptations?
If so, does it apply to your compound?

4. examples Lithium chloride Chart says ‘soluble’ LiCl
Anion is chloride (Cl)
Chart says ‘soluble’
The exceptions are Ag, Pb and Hg
Li is NOT an exception
LiCl is soluble

5. Complete the predicting solublity worksheet
We will go over answers on Thurs but the sub will write down who completed it and who did not.

6. Writing Net Ionic Equations
Write a balanced molecular equation.
Dissociate (break apart anything soluble) all strong electrolytes.
Cross out anything that remains unchanged from the left side to the right side of the equation.
Write the net ionic equation with the species that remain.

7. Ionic Equation
In the ionic equation all strong electrolytes (strong acids, strong bases, and soluble ionic salts) are dissociated into their ions.
This more accurately reflects the species that are found in the reaction mixture.
Ag+ (aq) + NO3- (aq) + K+ (aq) + Cl- (aq) 
AgCl (s) + K+ (aq) + NO3- (aq)

8. Net Ionic Equation
To form the net ionic equation, cross out anything that does not change from the left side of the equation to the right.
Ag+(aq) + NO3-(aq) + K+(aq) + Cl-(aq) 
AgCl (s) + K+(aq) + NO3-(aq)

9. Ag+(aq) + Cl-(aq)  AgCl (s)
Net Ionic Equation
To form the net ionic equation, cross out anything that does not change from the left side of the equation to the right.
The only things left in the equation are those things that change (i.e., react) during the course of the reaction.
Ag+(aq) + Cl-(aq)  AgCl (s)

10. Net Ionic Equation
To form the net ionic equation, cross out anything that does not change from the left side of the equation to the right.
The only things left in the equation are those things that change (i.e., react) during the course of the reaction.
Those things that didn’t change (and were deleted from the net ionic equation) are called spectator ions.
Ag+(aq) + NO3-(aq) + K+(aq) + Cl-(aq) 
AgCl (s) + K+(aq) + NO3-(aq)
