Chapter 14, Problem 103CQ(choose chapter or problem)
One of the most acidic lakes in the United States is Little Echo Pond in the Adirondacks in New York. Recently, this lake had a pH of 4.2, well below the recommended pH of 6.5. (10.3, 10.4, 10.5) A helicopter drops calcium carbonate on an acidic lake to increase its pH.a. What are the [H3O+] and [OH?] of Little Echo Pond?b. What are the [H3O+] and [OH?] of a lake that has a pH of 6.5?c. One way to raise the pH of an acidic lake (and restore aquatic life) is to add limestone (CaCO3). How many grams of CaCO3 are needed to neutralize 1.0 kL of the acidic water from Little Echo Pond if we assume all the acid is sulfuric acid?H2SO4(aq) + CaCO3(s) ? CO2(g) + H2O(l) + CaSO4(aq)
