Potassium nitrate is a chemical compound with a sharp, salty, bitter taste and the chemical formula K N O. 3. It is an ionic salt of potassium ions K + and nitrate ions NO 3−, and is therefore an alkali metal nitrate. It occurs in nature as a mineral, niter (or nitre outside the US). [ 5]
The results from the study on Lake Constance found that nitrate was depleted in the water at the same depth as methane, which suggests that methane oxidation was coupled to denitrification. It could be inferred that it was M. oxyfera -like bacteria carrying out the methane oxidation because their abundance peaked at the same depth where the ...
Aqua regia ( / ˈreɪɡiə, ˈriːdʒiə /; from Latin, "regal water" or "royal water") is a mixture of nitric acid and hydrochloric acid, optimally in a molar ratio of 1:3. [b] Aqua regia is a fuming liquid. Freshly prepared aqua regia is colorless, but it turns yellow, orange or red within seconds from the formation of nitrosyl chloride and ...
Elevated nitrate in groundwater is a concern for drinking water use because nitrate can interfere with blood-oxygen levels in infants and cause methemoglobinemia or blue-baby syndrome. [28] Where groundwater recharges stream flow, nitrate-enriched groundwater can contribute to eutrophication , a process that leads to high algal population and ...
Freshwater acidification. 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.

Infobox references. Nitrate is a polyatomic ion with the chemical formula NO−. 3. Salts containing this ion are called nitrates. Nitrates are common components of fertilizers and explosives. [1] Almost all inorganic nitrates are soluble in water. An example of an insoluble nitrate is bismuth oxynitrate .
Amyl nitrite. Amyl nitrite is a chemical compound with the formula C 5 H 11 ONO. A variety of isomers are known, but they all feature an amyl group attached to the nitrite functional group. The alkyl group is unreactive and the chemical and biological properties are mainly due to the nitrite group. Like other alkyl nitrites, amyl nitrite is ...
The state water board plans to decide whether to intervene in Kern County at a Feb. 20 meeting, after considering whether to take similar measures in two other areas of the San Joaquin Valley, the ...
