Question

I'm doing a report for my class, and for some reason, I'm having trouble finding these...

How will an increase in the concentration of limestone affect the pH of groundwater?
Can the compostition of the soil have an effect on the limestone's ability to neutralize?
Where does most acid rain fall in the United States?
Where are limestone soils found in Virginia?
What is always produced when an acid reacts with a base?

Answer 1

1) Limestone will decrease the pH of water if it is acidic. It is used in acidic groundwater clean-up sites. (like abandoned coal mines)

2) Soils that are very very acidic will create very acidic groundwater and it could stand to reason that the limestone could only lower the pH so much.

3) Acid rain falls mostly in places where a large amount of sulfur and nitrous oxides are produced such as areas with large amounts of traffic or coal burning power plants (Los Angeles, Knoxville, etc.)

4) I live in Virginia and I am not sure about limestone soils. A lot of the western portion of Virginia is comprised of limestones so it would be safe to reason that a lot of the soil have limestone in them.

5) The end result of a reaction of any acid and any base is some kind of a salt and water.
