The pH of a particular raindrop is 5.6. (a) Assuming the major species in the raindrop are H2CO3(aq), HCO3-(aq), and CO32-(aq), calculate the concentrations of these species in the raindrop, assuming the total carbonate concentration is 1.0 Ɨ 10-5 M. The appropriate Ka values are given in Table 16.3. (b) What experiments could you do to test the hypothesis that the rain also contains sulfur-containing species that contribute to its pH? Assume you have a large sample of rain to test.

Calculate the pH of each of the following solutions:

You measure the pH of a 200 gallon pond and find that it is 5. You suspect that the pH dropped because of nitric acid from acid rain. Nitric acid (NHO3) is a strong acid. Assuming that the pH of the water was originally 6.5, calculate the mass of nitric acidic that was added to the pond. Assume that there is no buffer in the water. (MW N = 14 g/mole, H = 1 g/mole, O = 16 g/mole) The asnwer is supposed to be 0.462 grams of NHO3
