2016年11月1日 · When a laboratory reports directly the concentration of nitrate, it is referring specifically to the nitrate ion, which is designated chemically as NO3-. Most labs and advisors consider a level of 9,000 to 10,000 parts per million of the nitrate ion to …

2009年7月22日 · Nitrate is a nitrogen oxoanion formed by loss of a proton from nitric acid. Principal species present at pH 7.3. It is a nitrogen oxoanion, a member of reactive nitrogen species and a monovalent inorganic anion. It is a conjugate base of a nitric acid. Nitrate is a metabolite found in or produced by Escherichia coli (strain K12, MG1655).

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.

2023年10月11日 · The nitrate ion is the most important nitrogen source for plants and vegetable crops. In this article, we have discussed everything you need to know about the nitrate [NO 3] – ion, including how to draw its Lewis dot structure, what is its molecular geometry or shape, electron geometry, bond angle, hybridization, formal charges, polarity, etc.

2023年10月31日 · Some check specifically for the concentration of nitrate, measured by the nitrate ion (NO3-). Others check for the amount of nitrogen that is in the nitrate ion and call it nitrate nitrogen (NO3-N). “Nitrate is one part nitrogen plus three parts oxygen, so nitrogen only makes up about 22.6% of the nitrate ion,” Anderson explained.

I understand how the nitrite NOX2 N O X 2 ion can be formed and have a negative charge, but the nitrate NOX3 N O X 3 ion is confusing me. I made some simple drawings to try to explain what I don't understand: Does the "electron from outside" that the oxygen receives, as indicated in the drawing, comes from the nitrogen atom?

2021年7月14日 · Did you know that nitrate in high concentrations can contribute to the blood disorder illness methemoglobinemia in infants? The Australian Drinking Water Guidelines (ADWG) health limit is 50mg/L (as NO­ 3). However, many labs report Nitrate (as N). It is important to compare the correct form to the guideline.

2025年3月10日 · Nitrate (NO3) is a compound of nitrogen and oxygen naturally found in air, soil, water, and some food. Plants and animals require nitrates for their survival and growth, and the human body also produces this compound. In industry, nitrate is …

Nitrate (NO 3) and Nitrite (NO 2) are nitrogen-containing compounds that can be found in water and soils. The presence of nitrate and nitrite generally indicates contamination from a pasture, manure pile, decomposed vegetation or agricultural fertilizers, or sewage, though it may come from erosion of natural deposits.

The webpage provides the formula and structure of the nitrate ion (NO3-) with a molecular model.
