Chapter 12 Basics of Chemistry
Learning Objectives:
Explain the difference between organic and inorganic chemistry
Describe the different states of matter: solid, liquid, and gas
Describe oxidation-reduction (redox) reactions
Explain the differences between pure substances and physical mixtures
Explain the difference among solutions, suspensions, and emulsions
Explain ph and the ph scale
Vocabulary
Review Questions/Reading Minute
Theory Workbook
Practical Workbook
Group Work/Collaborative Learning/Activities- Put a tablespoon of sugar in a
cup of hot water. Cover it loosely with a paper towel and set it aside for a
week. What happens when the water evaporates? What are the crystals that form
inside of the cup made from? Taste them and see whether your conclusions were
right. When sugar dissolves in water, is it a physical or chemical change?
Oil and water activity-Have you ever heard the saying "Oil and water don’t
mix"? Pour some water into a glass, and then add a little cooking oil. What
happens? Stir the water briskly with a spoon and observe for a minute or two.
What does the oil do?
Revisit the PH SCALE
