One strategy for dealing with the acidification of lakes is periodically to add powdered limestone (CaCO3) to them. Calculate the pH of a lake that has more than enough powdered limestone in it to saturate the water with its ions Ca2+ and CO32-. The [CO2] in the lake is 1.2*10-5 mol/L. Suggestions: Begin with the carbonate systems equations and then add a charge balance equation: [H+]+2[Ca 2+] = [HCO3 -]+2[CO3 2-]+[OH-] appr. = [HCO3 -]+[OH-] The preceding holds for pH values that are less than about 10, when you work out the solution check to see whether this was a valid assumption.

Answer:

Ph of lake = 8.3

Explanation:

Calculate the PH of a lake that has more than enough powered limestone in it  to saturate the water with its ions

First we will calculate the saturated value of CO2 (aq)

[ CO2 (aq) ] = K

Answer:

One strategy for dealing with the acidification of lakes is to periodically add powdered limestone (CaCO3) to them. In this instance it is assumed that the lake in question has more than enough powdered limestone in it to saturate the water with its ions Ca2+ and CO32- Write the charge balance equation for this system.
