Differbetween
Nitrogen can be found circulating in the nitrogen cycle in different forms whereas nitrate ion can be found in the steps of nitrification and denitrification. The main difference between nitrogen and nitrate is that nitrogen is a chemical element whereas nitrate is an anion.

How do you convert nitrogen to nitrate?
The reason for this conversion is that nitrate molecule weighs 62 grams per mole; the nitrogen content of nitrate is 22.5% of the total weight of the molecule.
...
Conversion between nitrate (NO3) and nitrate-nitrogen (NO3-N):
| To convert | To | Multiply by |
|---|---|---|
| Nitrate-nitrogen (NO3-N) | Nitrate (NO3) | 4.43 |
What is the difference between NO3 and NO3-N?
When a laboratory reports directly the concentration of nitrate, it is referring specifically to the nitrate ion, which is designated chemically as NO3-. ... Some labs, though, report the amount of nitrogen that is in the nitrate ion and call it nitrate nitrogen and report it chemically as NO3-N.
What is nitrate used for?
What are nitrates? Nitrates (or nitrites) are natural chemicals that are found in the soil, air and water. Nitrates are also used as a food additive to stop the growth of bacteria and to enhance the flavour and colour of foods.
What does NO3-N mean?
Levels of nitrate can be expressed in either of two ways: “nitrate as nitrogen” (symbol: NO3-N) or simply as nitrate (NO3). To convert NO3-N to NO3 in parts per million (ppm, or mg/L), multiply NO3-N by 4.42.
How do you calculate nitrates?
The nitrate concentration is calculated by subtracting the absorbance at 275nm from the absorbance at 220nm and then comparing the corrected absorbance to a calibration curve developed using standards of known nitrate concentration (APHA, 2005).
Is nitrogen a gas?
Nitrogen (N), nonmetallic element of Group 15 [Va] of the periodic table. It is a colourless, odourless, tasteless gas that is the most plentiful element in Earth's atmosphere and is a constituent of all living matter.
How is organic nitrogen converted to ammonia?
Ammonification. When an organism excretes waste or dies, the nitrogen in its tissues is in the form of organic nitrogen (e.g. amino acids, DNA). Various fungi and prokaryotes then decompose the tissue and release inorganic nitrogen back into the ecosystem as ammonia in the process known as ammonification.
What is the charge of nitrate?
Nitrate, chemical formula NO3, has a chemical charge of -1. Ion nitrates have a negative one formal charge. You may be wondering why this is the case.
What is a safe level of nitrite in drinking water?
In the United States the EPA, under the authority of the Safe Drinking Water Act (SDWA), has set the Maximum Contaminant Level Goal (MCLG) for total nitrate/nitrite at 10.0 mg/L and for nitrite at 1.0 mg/L (measured as nitrogen, N).
What food is high in nitrates?
DIETARY SOURCES OF NITRATE AND NITRITE
| Nitrate content (mg/100 g fresh weight) | Vegetable varieties |
|---|---|
| Middle, 50 to <100 | Cabbage, dill, turnip, savoy cabbage |
| High, 100 to <250 | Celeriac, Chinese cabbage, endive, fennel, kohlrabi, leek, parsley |
| Very high, >250 | Celery, cress, chervil, lettuce, red beetroot, spinach, rocket (rucola) |
Are Bananas high in nitrates?
Banana, broccoli, cabbage, cucumber, potato crisps, pumpkin, salami and strawberries also contain nitrates, but at lower concentrations of between 100 to 450mg/kg.
What are the side effects of nitrates?
Common side effects:
- Dizziness.
- Headaches.
- Flushing of your face and neck.
- Upset stomach or throwing up.
- Low blood pressure (hypotension)
- Irregular heart rhythms (arrhythmia)
