1. Reactions in Solutions

2. Reactions in Solution
When combining two aqueous ionic solutions there are two possible outcomes:
The solutions do not react and remain in solution
The solutions react (double displacement) forming either
A precipitate
A gas
Water

3. Precipitation Reactions
To determine if a precipitate will form you will need to use a solubility table.
General solubility rules:
All nitrates (NO3-) are soluble
All group 1 compounds, including acids, are soluble
All ammonium (NH+) compounds are soluble
All acetates (CH3COO-) are soluble except in compounds with silver (Ag+)
Carbonates (CO32-), phosphates (PO43-) and sulfites (SO32-) will precipitate except in compounds with Rules #2 & #3
For all other exceptions, refer to a solubility table

4. Will the following solutions produce a precipitate?
Practice
Will the following solutions produce a precipitate?
A. potassium carbonate and cuprous sulfate
B. ammonium chloride and sodium sulfate

5. Reactions Producing a Gas
Remember your gas tests?
Oxygen
Hydrogen
Carbon dioxide

6. Reactions Producing Water
Neutralization reactions
Acid + base  salt + water
pH tests (litmus paper, phenolphthalein, bromothymol blue)
