<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. H<sub>2</sub><nowiki>SO</nowiki><sub>4</sub> <br> <br> <br> 4. Sulfurous acid<br> <br> <br> 5. Ca<sub>1</sub>(OH)<sub>2</sub><br> <br> <br> 6. Phosphoric acid<br> <br> <br> 7.

H<sub>1</sub>NO<sub>2</sub><br> <br> <br> <br> <br> <br> Part II - Please answer the following with appropriate vocabulary and complete sentences where appropriate.<br> <br> 1. 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> <br> 2. What does a pH indicate do and how does the compound do it?<br> <br> <br> <br> 3. Why do you use a pH indicator in an Acid - Base titration. When you do use this, what calculation are use allowed to use then to help you find the unknown substance's Molarity or Volume <b>(2016-2017 students do not do</b>.<br> <br> <br> <br> <br> 4. Write down the mathematical equation to determine pH. How are the pH and [H<sup>1+</sup> related, direct or indirect proportion? What in the math equation determines this?<br> <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> 4. 455ml of a 0.452M Sulfuric acid solution is neutralized with a 0.150M sodium hydroxide solution. How many liters of the sodium hydroxide solution to complete neutralize all the acid? <b>(2016-2017 students do not do</b><br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br>
