Directions:
Add one drop of chemical from each column and row to the corresponding box. To be sure that the drops mix, put
them on top of one another so the result is just one spot of chemical.
Be sure the dropper bottle tip doesn’t touch the drop.
Cleaning: To clean this grid, blot with a dry paper towel, then use a moist paper towel to clean any remnants off
of the plastic.
Writing Ionic Formulas Lab Activity
Background
When two compounds composed of ions combine, sometimes new compounds are
formed. In this activity you will be combining ionic compounds and then, will predict
the formulas and names of new compounds.
Directions
1. Locate the chemicals and grid.
2. Drop one drop of each chemical on the corresponding square. Place drops of
different chemicals directly on top of each other so the result is a larger drop on
the plastic. Be sure the dropper bottle tip doesn’t touch the drop.
3. Observe the reaction and record the physical properties. (Color, opacity)
4. Record the formula of the new compound.
5. Record the name of the new compound.
