An 8000 m3 lake has a pH of 4. For this problem, assume no water is added or withdrawn from the lake.

a. What is the molarity of H+ in the lake?

b. How many moles of OH- would be needed to raise the pH of the lake to 6?

c. One method for neutralizing acids in surface water is to add lime (CaCO3). Write a balanced equation for the neutralization of H+ with limestone.

d. If this OH- all comes from limestone, how many kg of limestone will be needed? Assume that all of the limestone reacts with H+.
