Common sources of chemical burns include sulfuric acid (H 2 SO 4), hydrochloric acid (HCl), sodium hydroxide (NaOH), lime (CaO), silver nitrate (AgNO 3), and hydrogen peroxide (H 2 O 2). Effects depend on the substance; hydrogen peroxide removes a bleached layer of skin, while nitric acid causes a characteristic color change to yellow in the ...
For superficial injuries, washing (therapeutic irrigation) is important.Emergency treatments include protecting the airway, which might involve a tracheostomy.Further treatment will vary depending on the severity, but might include investigations to determine the extent of damage (bronchoscopy for the airways and endoscopy for the gastrointestinal tract), followed by treatments including ...

Piranha solution, a dangerous mixture of sulfuric acid and hydrogen peroxide known to aggressively dissolve organic material, draws its name from these legends surrounding the piranha fish. A common falsehood is that they can be attracted by blood and are exclusively carnivores. [41]

Sulfuric acid and nitric acid have multiple impacts on aquatic ecosystems, including acidification, increased nitrogen and aluminum content, and alteration of biogeochemical processes. [73] 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.
It is generated on site by reacting potassium cyanide or sodium cyanide with sulfuric acid (e.g., in a modern American gas chamber). Fumes arise during a building fire or any similar scenario involving the burning of polyurethane, [21] vinyl [22] or other polymer products that required nitriles in their production.
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.
