NAMES & FORMULAS FOR IONIC COMPOUNDS LAB
PURPOSE: The purpose of this experiment is to observe the formation of compounds
and to write their names & formulas correctly. Just because you put two chemicals
together does not mean that they will react.
SAFETY:
 Wear safety goggles at all times.
 Call teacher in case of spill.
 DO NOT touch any chemicals.
 Wash hands with soap.
Materials:
 0.05 M AgNO3
 0.10 M Na3PO4
 0.10 M FeCl3
 0.20 M Pb(NO3)3
 0.50 M NaOH
 0.20 M MgSO4
 0.50 M CaCl2
 0.20 M Na2SO4
 A 12-well spot plate
 1.0 M Na2CO3
 0.20 M CuSO4
PROCEDURE:
1. Align the spot plate the same as DATA TABLE A. This makes it easier to
remember where to place the chemicals!)
2. Place 4 drops of each solution in the appropriate wells (moving across from left to
right & top to bottom). This will combine 2 chemicals in each well.
3. Observe to see if any reaction takes place. A reaction is observed when a solid
forms, an odor appears, a color changes, etc.
4. Record your results in DATA TABLE A in your lab notebook. (NOTE: a solid that
forms is known as a precipitate.)
5. Clean your spot plate into the trash can NOT THE SINK. Then wash your spot
plate.
6. Repeat Step 2 with the chemicals from DATA TABLE B. (You will only be changing
the compound in the columns.)
7. Record your observations in DATA TABLE B in your lab notebook.
8. Clean out your spot plate by dumping & wiping all solids INTO THE TRASH CAN.
Then wash the spot plate out.
9. Return all equipment & supplies to original location.
Data Table: Combine the reactant in the first column with the reactant in the second
column. Write down the names of the two products formed by the double replacement
reaction and any observations you saw that indicate that a reaction occurred. If no
reaction occurs, write NR (No Reaction).
