CHEMICAL FORMULA LAB
In this lab, we will be using five ionic compounds. Two of the compounds are nitrate containing compounds
and will be separately placed in a well with each of the remaining three compounds.
Purpose: The purpose of the lab is to look for evidence of chemical reactions and to write the balanced
chemical equations, showing what took place in each of the wells.
1. How will you know if a chemical reaction has taken place?

Compound Chemical Cation Anion
Formula
silver nitrate
lead (II) nitrate
iron (II) chloride
potassium iodide
sodium hydroxide
Procedure
1. Obtain a well plate.
2. Each of the nitrate compounds will be mixed with each of the other compounds.
2. Use 3 drops of each compound for each separate reaction.
3. Record all observations in the data table.
Safety
1. Do not mix any chemicals that are not called for in the procedure.
2. Wear safety goggles at all times.
3. Many of these chemical compounds will stain clothes and skin, so be cautious with their use.
4. Be sure to always tightly screw the dropper top on the bottle to avoid spills.
Clean up
1. When you have finished, carefully rinse the well plate.
2. Wipe down your lab table and wash your hands.

CONCLUSIONS
On the first line, write the word equation for each reaction and what type of reaction took place.
On the second line, write the balanced chemical equations for each reaction that took place in the wells above. If no reaction occurred,
write NR after the reactants. Be sure to include states of matter (s, l, g, aq).
