During the lab, you measured the pH of common household items. Use this knowledge to answer the following questions. (a) A 0.0010 M solution of HC7H5O2 has a pH of 3.60. What is the [H3O+ ]?
M (Answer to 2 significant figures.)

(b) A 0.0010 M solution of HClO4 has a pH of 3.00. What is the [H3O+ ]?
M (Answer to 2 significant figures.)

(c) Based upon these measurements, HC7H5O2 is a ---Select--- weak strong acid and HClO4 is a ---Select--- weak strong acid.

Write net Brønsted equations that show the acidic or basic nature of the following substances, given the pH. For polyprotic acids, only show one proton transfer. Remember that spectator ions are not included. (Use the lowest possible coefficients. Omit states-of-matter in your answer.)
