2. Determine if Drano is an acid or base and describe how it works to clean clogged drains.
3. Describe the process of naming binary and oxyacids from a given chemical formula.
4. Describe the process of creating the chemical formula of a binary and oxyacid from a given name.
5. Acids and bases are classified in several different ways based on specific characteristic chemical
behaviors. What characteristics are used to group acids and bases into the following categories:
Arrhenius acid:
Arrhenius base:
Bronsted-Lowry acid:
Bronsted-Lowry base:
Lewis acid:
Lewis base:

When various acids or bases ionize in aqueous solutions to release, respectively, an H+ or OH-, the
ionization occurs more or less “easily” depending on the strength of the acid or base.
6. Describe why you can consume vinegar while this is not recommended with a dilute solution of
battery acid.

8. The term “protic” refers to protons (hydrogen ions). What is meant when an acid is referred to as
monoprotic, diprotic, or triprotic Give examples to illustrate your explanation.
9. The Bronsted-Lowry definitions of acids and bases provide a basis for studying proton transfer in
acid-base reactions. Two terms, conjugate acid and conjugate base, are a part of the nomenclature
associated with this study. What are conjugate acids and bases Provide a reaction formula equation
to illustrate your answer.
10. Ka and Kb are mathematical constants derived from the equilibrium concentrations of conjugate acids
and bases found in aqueous solutions as compared against the equilibrium concentrations of the parent
acid or base. How do these constants relate to the relative strengths of a series of acids or bases
11. Combining a strong acid with a strong base results in a neutralization reaction. Why is the term
“neutralization” applied to this reaction
12. Acid rain creates problems with crop production. Using your understanding of how acid rain
develops and how it hinders agricultural processes, propose a means for eliminating the acid rain
problem.

13. What is meant by “the self-ionization of water”
14. What is the difference between a hydrogen ion, a hydronium ion, and a hydroxide ion, and how are
they produced when water self-ionizes
15. How is the Kw constant developed, and under what conditions is it valid
16. Using the Kw equation, how is it possible to determine whether an aqueous solution is acidic, basic,
or neutral
17. There are several ways to express the acidity or basicity of a solution. Probably the most common
means is by using pH. How is the numerical value of pH determined, and how does its magnitude
relate to acidity or basicity
18. How might you use an acid-base indicator to determine if the pH of the water in your fish tank was
suitable for your pet fish Should the environment for fish be acidic, basic, or neutral What
indicator might you use to determine if your tank is suitable How might a tritration be useful in this
process
19. The endpoint of bromothymol blue is at around a pH of 7. The equivalence point of acid Solution A
and basic Solution B is at a [H+] = 1.2 X 10-7. Is this a good indicator for this titration
20. Given the same solutions as the previous question, would methyl orange be a good indicator for this
titration Explain your answer.
21. The concentration (molarity) of an acid solution is not the same as the strength of the acid. What is
the difference
