Question

2. Use the log C-pH diagram for the open carbonate system that you created in problem 1 above to compute the pH of natural rainwater. Write down the relevant expressions for (a) charge balance and (b) the proton condition.Compare this with the analytical solution for the pH of natural rainwater shownin Example 2.12 of the Masters' ENV 3001 text, and the class notes from earlier lecture on the pH of natural unpolluted rain versus acid precipitation.
