Name: ____________________________ Period: ______

Part I For the following questions, please give the appropriate chemical name or chemical formula (show work including the information required above). Also, state if it is a strong electrolyte, weak electrolyte or non-electrolyte.

1. H2S

2. Hydroselenic acid

3. H2SO4

4. Sulfurous acid

5. Ca1(OH)2

6. Phosphoric acid

7. Ammonia

8. C1O2

9. Ba1(ClO2)2

10. H1NO2

Name: ______________________ Period: _____

Part II - Please answer the following with appropriate vocabulary and complete sentences where appropriate.

1. What are the 7 strong acids (give name and chemical formula for each).

2. Define what an Arrhenius acid is.

3. Even though it is not suggested to do for alot of acids, what do they "taste" like?

4. What is the major difference between a strong acid and a weak acid with respect to determining concentration of [H1=]?

5. True or False, all salts (general name for an ionic compound) are weak electrolytes.

6. What is the definition of an Arrhenius base?

7. What are the strong bases?

8. Just like in Question 3, what is the "taste" of a base? What is the other properties of base that is not a property of an acid.

9. What is the major difference between a strong and weak base with respect to the concentration of [OH1-].

10. True or False, solutions with a pH > 7 is considered an acidic solution?
11. True or False, in a basic solution, there are "no" (not even a very small Molarity) of hydronium ions ([H1+])?

12. How does the pH value and the concentration (in M) of hydronium ([H1+]) ion relate to each other.

13. If you go down 1.0 pH unit, how does the amount of concentration (in M) of hydronium ([H1+]) ion change?

14. There is a 1.0M H2SO4 solution, 1.0M HCl solution and a 1.0HF solution. It was found that the relative pHs of the solution went from lowest, middle, to highest, respectively. Explain why the pH range was true for the three solutions.

Name: ___________________________ Period: ____

Part III - Please answer the following questions showing all appropriate work.

1. What is the pH of a 5.14E-3M Carbonic acid solution (assume it is a strong acid).

2. What is the concentration (in M) of a calcium hydroxide solution that has a pOH of 3.145?

3. What is the pH of a 5.3E-4M sodium hydroxide solution?

4. What is the pOH of a 2.4E-3M sulfuric acid solution?
