Experiment 262: Chemical Reactions
Purpose
At the heart of chemistry are chemical reactions. Chemical reactions begin with one set of
materials and end up with different materials. The purpose of the experiment is to observe
precipitation and neutralization reaction while using the data to identify metal ions in an
unknown sample.
Procedure
• Place about one milliliter (20 drops) of each solution into a test tube. Mix using a
vortexer very well for each compounds
• Test compounds Barium nitrate, 0.1 M with ammonium chloride, 3M
• Test compound Calcium nitrate, 0.1 M with sodium carbonate, 1M
• Iron (III) nitrate, 0.1 M with sodium hydroxide, 3M
• Silver nitrate, 0.1 M test with sulfuric acid, 3M
