Home Experiment:
Polar and Nonpolar Substances
(21 points)
Purpose: To determine which household substances are polar and
which are nonpolar..
Procedure:
- Choose various household substances (both liquids and solids) to
test the polarity of.
- Try to choose things that are compounds and not mixtures.
- Examples of liquids: water, vegetable oil, gasoline, paint
thinner, mineral spirits, terpentine, antifreeze, rubbing alcohol,
hydrogen peroxide, brake parts cleaner, acetone
- Examples of solids: salt, sugar, baking soda, washing soda,
epsom salts, moth balls, wax, crisco
- Research what polarity is how polar compounds interact with
nonpolar compounds.
- Write a procedure to test various household substances for
polarity. (Test both liquids and solids)
- Use your procedure to test the substances, and tell how you know
whether they are polar or nonpolar.
Lab Report:
- Should Include:
- Introduction - Research what polarity is and give a
summary
of polarity and what you’ve learned about it that helped you design
this
experiment.
- Methods section describing your
procedure
- Results section (should have a chart showing your
recorded data and results of whether each is polar or nonpolar).
- Discussion section talking about your results. How
accurate
do you think your results are? Can you see any patterns in your
results
about what types of things tend be polar or nonpolar?
- Works Cited page listing your sources you cited
(in proper MLA format).
