3. Combine chemicals specified in the chart.
Figure out a way to keep track of the chemicals.
Use a ¼ scoop for solids (the less, the better).
Use 1 squeeze of an eyedropper for solutions.
4. Write chemical equations for chemicals that
reacted. Write NR where there was no reaction.
5. Dump used chemicals into the large funnel at
the front of the room (use a squirt bottle to rinse
remaining chemicals into the funnel). Wash the
spot plate and glass rod very well. Dry & return.
