Part II - Please answer the following with appropriate vocabulary and complete sentences where appropriate.
1. 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.
2. What does a pH indicate do and how does the compound do it?
3. Give one characteristic of an acid? Give one characteristic of a base? Do not use what color acid/base turns litmus paper?
4. Write down the mathematical equation to determine pH. How are the pH and [H1+] related, direct or indirect proportion? What in the math equation determines this?
5. How is a solution of a strong acid (e.g. HCl ) differ from a solution of a weak acid (e.g. HF)? Explain.
6. In a basic solution, there is no H1+ in the solution. True or False. Explain.
7. What are the three different types of definition of acid/base.
a)
b)
c)
