Green checks and red X's are not displayed for part (c) of this question. During the lab, you measured the pH of common household items. Use this knowledge to answer the following questions. (a) A 0.00010 M solution of H, SO 4 has a pH of 4.00. What is the [H20+ ]? M (Answer to 2 significant figures.)
(b) A 0.00010 M solution of HBrO has a pH of 6.33. What is the [H20+ ]? M (Answer to 2 significant figures.)
(c) Based upon these measurements, H 504 is a ---Select--- 7 acid and HBro is a ---Select--- 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.) chemPad Help X. X" - = Greek
(d) tums antacid (calcium carbonate) with a pH of 8.50 chemPad Help X. X" === Greek (e) grapes (tartaric acid, H, CHOR) with a pH of 2.90
