Pure water is said to be neutral, with a pH close to 7.0 at 25 °C (77 °F).
Solutions with a pH less than 7 are said to be acidic and solutions with a pH greater than 7 are basic or alkaline.
Acid ground water is water in the rocks that has a pH of 2 to 6.

Opening formed when acid groundwater dissolves limestone?
a cave
What is the opening formed when acid groundwater dissloves limestone?
A cave or sinkhole.
What acid is most commonly present in groundwater?
Probably carbonic acid, which is formed when carbon dioxide dissolves in water. There are other acids that can be found in nature, but the concentration of carbon dioxide in the atmosphere is far higher than the concentration of (for example) nitrogen or sulfur oxides, which can also form acids when dissolved in water.
What is water that is not absorbed by soil?
Groundwater.
Which rock type is most easily dissolved by groundwater?
limestone
What acid does groundwater naturally contain?
Groundwater usually contains carbonic acid.
Opening formed when acid groundwater dissolves limestone?
a cave
What is the opening formed when acid groundwater dissolves limestone called?
A cave?
What is the opening formed when acid groundwater dissloves limestone?
A cave or sinkhole.
What does groundwater naturally contain that allows it to dissolve limestone and caverns?
Carbonic Acid
What does groundwater naturally contain that allows it to dissolve limestone and form caverns?
Carbonic Acid
Caves and caverns are formed in carbonate rocks by?
The reaction of carbonic acid in rain and groundwater with the carbonate rock.
Is water in caves acidic?
yes, because it is formed by groundwater charged with CO2 (carbon dioxide) which forms carbonic acid
What is formed when groundwater mixes with carbon dioxide from air?
when groundwater mixes with carbon dioxide from the air it forms Carbonic Acid.
How does groundwater cause chemical weathering?
Groundwater causes chemical weathering by speeding reactions between reactive materials. Typical would be an oxidizing reaction, such as the formation of rust in rocks containing iron, or the dissolution of limestone by carbonic acid.
What is least likely to be a source of groundwater pollution?
is it agricultural runoff households dumping acid rain over pumping of water from wells
What has the author David R Lee written?
David R. Lee has written: 'Evaluation of an underwater monitoring probe for locating and estimating the impact of groundwater discharges to surface waters adjacent to potential sources of acid mine drainage' -- subject(s): Hazardous waste sites, Acid mine drainage, Leaching, Groundwater flow, Seepage
