Well 5:
Well 6:
3. Add NaCl to row 1, wells 1 through 6. Observe the wells for a few minutes. Record your observations in
data table 1. Write NR if no reaction occurs.
4. Repeat step 2 using each of the following
Row 2: Na3PO4
Row 3: Ca(OH)2
Row 4: Na2CO3
5. Mix well and record observations. If a reaction occurred, students should write a complete and balanced
equation in the analysis section of the lab. If no reaction occurred, they should record "no reaction."
6. Discard the mixtures from the well plates in a waste jar. Students should not pour their solutions in the
sink.

Analysis: Write balance chemical equations for each of the reactions observed.
Write out the balanced equations that occurred for each reaction that you performed in this lab. If no
reaction occurred, you do not need to write out an equation, write NR instead.
