Unit Objectives:
- Compare and contrast the physical and chemical properties of acids and bases.
- Define and compare acids and bases using Bronsted-Lowry, Arrhenius (Traditional), and Lewis definitions.
- Classify substances as acids, bases or neutral based on the three acid base theories.
- Name, with 100% accuracy, binary and oxyacids.
- List three common acids that are used for industrial purposes, and what such purposes are.
- Identify, define, and describe conjugate acid-base pairs.
- Explain the behavior of water when it self-ionizes, and apply the equation based upon this behavior (Kw).
- Describe the pH scale and solve for hydronium and hydroxide ion concentrations, pOH and pH.
- Describe the pOH scale and solve for hydronium and hydroxide ion concentrations, pOH and pH.
- Assess the strength of an acid or base on the basis of its pH or pOH value.
- Predict the products that are created from an acid reacting with a base.
- Discuss why acid-base reactions are called neutralization reactions.
- Compare and contrast acid-base neutralization reactions amongst a set of given chemical reactions.
- Describe indicators and explain how they change color based upon the acidity of the environment.
- Identify the conjugate acid - base pairs of the Bronsted-Lowry Theory.
- Identify monoprotic, diprotic and triprotic acids.
- Describe and perform an acid-base titration, and use the experimental data to determine solution concentration.
- Explain the species that are present in the reaction vessel at any point during the titration.
- Explain how indicators are used in titrations.
- Teach another student how to perform a titration.

Sig Figs rules are not stressed here . . .
When applying a logarithm, you increase sig figs by one.
When applying the InverseLog, you decrease sig figs by one.
