5. List 5 strong acids. You can use name or chemical formula. 6. Nitrous acid (HNO 2 ) is a weak acid. When a 0.5 M aqueous solution of nitrous acid reaches equilibrium, the pH is measured to be 1.78. Using this information, calculate K eq (same as K a ) for nitrous acid. 10 pts 7. Identify the conjugate base of nitrous acid.

8. A 0.5 M solution of NaNO 2 is prepared. Its pH is measured. Is the pH more or less than 7? (Note: an answer of “more than 7” or “less than 7” will suffice. If you successfully calculated the K a for nitrous acid in problem #6, you can use it to calculate the exact pH of the solution and gain 5 extra points.) 10 pts 5 pts extra 9. A student makes up a 1.5 M solution of HCl. What is the pH of this solution? 10. A student makes up a 0.5 M solution of benzoic acid (C 6 H 5 COOH). The pK a of benzoic acid is 4.19.
