EXTRA CREDIT FOR TEST 2 - 1420-002 What is the pH of a 0.01 M solution of sulfuric acid? Hint: K a1 is "very large," K a2 is finite. No simplifying assumptions can be made, because K a2 >> 1 x 10 -5 . Give the answer to three significant digits, please (i.e., 3 places to the right of the decimal point). Turn in this assignment 12:00 noon, at the beginning of class, April 4, 2011. A correct answer will result in 1 correct answer in the April 1 test (e.g., if you miss 4 questions in the February 28 test, with a correct extra credit your hour test's score will be given credit for only 3 questions missed).
