Name: ____________________________ Period: ______<br> <br> <br> <b>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.</b><br> <br> <br> 1. H<sub>2</sub>S<br> <br> <br> 2. Hydroselenic acid<br> <br> <br> 3.

What are the 7 strong acids (give name and chemical formula for each).<br> <br> 2. Define what an Arrhenius acid is.<br> <br> <br> 3. Even though it is not suggested to do for alot of acids, what do they "taste" like?<br> <br> <br> 4. What is the major difference between a strong acid and a weak acid with respect to determining concentration of [H<sup>1=</sup>]?<br> <br> <br> 5. True or False, all salts (general name for an ionic compound) are weak electrolytes.<br> <br> 6. What is the definition of an Arrhenius base? <br> <br> <br> 7. What are the strong bases?<br> <br> 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.<br> <br> <br> 9. What is the major difference between a strong and weak base with respect to the concentration of [OH<sup>1-</sup>].<br> <br> <br> 10. True or False, solutions with a pH > 7 is considered an acidic solution? <br> 11. True or False, in a basic solution, there are "no" (not even a very small Molarity) of hydronium ions ([H<sup>1+</sup>])?<br> <br> 12. How does the pH value and the concentration (in M) of hydronium ([H<sup>1+</sup>]) ion relate to each other.<br> <br> <br> 13. If you go down 1.0 pH unit, how does the amount of concentration (in M) of hydronium ([H<sup>1+</sup>]) ion change?<br> <br> <br> 14. There is a 1.0M H<sub>2</sub>SO<sub>4</sub> 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. <br> <br> <br> <P style="page-break-before: always"> <br> Name: ___________________________ Period: ____<br> <br> <br> Part III - Please answer the following questions showing all appropriate work.<br> <br> <br> 1. What is the pH of a 5.14E-3M Carbonic acid solution (assume it is a strong acid). <br> <br> <br> <br> <br> <br> <br> <br> <br> 2. What is the concentration (in M) of a calcium hydroxide solution that has a pOH of 3.145?<br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> 3. What is the pH of a 5.3E-4M sodium hydroxide solution?<br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> 4. What is the pOH of a 2.4E-3M sulfuric acid solution?<br> <br> <br> <br> <br> <br> <br> <br>
