Big Ideas - Quantities in Chemistry
- Relationships in chemical reactions can be described quantitatively.
- Quantitative relationships of chemical reactions have applications in the home, workplace, and the environment.
Learning Goals for Quantities in Chemistry: The student will be able to
- define solutes, solvent and solution
- discuss properties of acids and bases
- explain the Arrhenius theory
- name acids and bases
- use experimentation to determine acid and base properties
- explain safety procedures
- calculate concentration as v/v, w/v, molarity, ppm and ppb
- distinguish between concentrated and diluted
- explain the difference between strong and weak solutions
- compare strengths vs concentration
- do dilutions calculations
- do dilutions
- explain pH
- explain how acids and bases are made
