Sulfuric acid and nitric acid have multiple impacts on aquatic ecosystems, including acidification, increased nitrogen and aluminum content, and alteration of biogeochemical processes. [70] Both the lower pH and higher aluminium concentrations in surface water that occur as a result of acid rain can cause damage to fish and other aquatic animals.
Diagram depicting the sources and cycles of acid rain precipitation. Freshwater acidification occurs when acidic inputs enter a body of fresh water through the weathering of rocks, invasion of acidifying gas (e.g. carbon dioxide), or by the reduction of acid anions, like sulfate and nitrate within a lake, pond, or reservoir.

Snow tends to contain more nitric acid than sulfuric acid, and as a result, a pulse of nitric acid-rich snow meltwater may leach through high elevation forest soils during a short time in the spring. [6] This volume of water may comprise as much as 50% of the annual precipitation.
It is a reactant in the atmosphere, where it acts as an aerosol, decreasing air quality and clinging to water droplets, eventually resulting in nitric acid (H NO 3) that produces acid rain. Atmospheric ammonia and nitric acid also damage respiratory systems. The very high temperature of lightning naturally produces small amounts of NO x, NH 3 ...
Commercially available nitric acid is an azeotrope with water at a concentration of 68% HNO 3. This solution has a boiling temperature of 120.5 °C (249 °F) at 1 atm. It is known as "concentrated nitric acid". The azeotrope of nitric acid and water is a colourless liquid at room temperature.
These are thought to be the principal pathways for formation of nitric acid in the atmosphere. [8]: 224–225 This nitric acid contributes to acid rain or may deposit to soil, where it makes nitrate, which is of use to growing plants. The aqueous phase reaction 2 NO 2 + H 2 O → HNO 2 + HNO 3
If you get acid reflux, an upset stomach, or other digestive issues after taking Cialis, making small changes — like drinking more water or using antacid medicine — can make this side effect ...
Yellow boy in a stream receiving acid drainage from surface coal mining. Water temperatures as high as 47 °C (117 °F) [9] have been measured underground at the Iron Mountain Mine, and the pH can be as low as −3.6. [10] Organisms which cause acid mine drainage can thrive in waters with pH very close to zero.
