Without doing a calculation, choose the answer that best describes the pH of a 0.01 M solution of H2SO4. Note that -log(0.01) = 2
a. The pH is slightly greater than 2.0
b. The pH is slightly greater than 7.0.
c. The pH is slightly less than 2.0.
d. The pH is slightly less than 7.0.
e. The pH is equal to 2.0.
Homework Answers
Here 1 mole of H2SO4 will furnish 2 moles of H+ ions. So concentration of H+ ions will be 0.02 M. So pH will be slightly less than 2. To be precise pH wll be -log0.02 = 1.7(not needed to know this answer).

Choose the answer that best describes the relative acidity of hypobromous (HBrO) and hypoiodous (HIO) acids. Note: although by convention the H is written first, it is actually attached to the oxygen in each case. A. HBrO is more acidic than HIO because Br is more electronegative than I. B. HBrO is more acidic than HIO because I is more electronegative than Br. C. HIO is more acidic than HBrO because I is larger than Br. D. HIO is more...
