How does nitrogen in the air and the soil converted into nitrates?
Nitrogen gas in the air is converted into nitrates through a process called nitrogen fixation by specialized bacteria. In the soil, nitrates are produced through nitrification, a two-step process involving the conversion of ammonium to nitrites and then to nitrates by bacteria.
What do nitrates indicate when found in a urine drug test?
Nitrates in a urine drug test may indicate a urinary tract infection (UTI). Nitrates are produced by certain bacteria in the urine, which are often associated with UTIs. Additional testing may be needed to confirm the presence of an infection.
How are nitrates produced?
Nitrate is mined from natural deposits of caliche ore . These deposits are mined primarily from saline mineral deposits that form veins and irregular masses in the bedrock. The ore is extracted by first drilling or blasting the soil overburden covering the deposits, then transported to the extraction plant. The overburden, usually 1 to 2 m thick, is removed mechanically and left on-site (Collings 1950). During refinement, crushed ore is dissolved at 35°C to extract nitrates, sulfates, potassium, and iodine. Nitrate precipitates are removed, crystallized, dried, and prilled.
How do nitrates get into urine?
Nitrates can enter urine through dietary ingestion of nitrates from foods such as leafy green vegetables, root vegetables, and processed meats. The body metabolizes dietary nitrates into nitrites, which are then excreted in the urine.
What is sentence for nitrates?
Nitrates are compounds often found in fertilizers and can also be naturally occurring in soil and groundwater. Excessive levels of nitrates in drinking water can be harmful to human health, particularly to infants and pregnant women.
Which nitrates are produced in nature?
oxygen and nitrogen
The process by which nitrites and nitrates are produced by bacteria in the soil?
Nitrites and nitrates are produced by nitrifying bacteria in the soil through a process known as nitrification. Ammonia or ammonium ions are first converted to nitrites by Nitrosomonas bacteria, and then further converted to nitrates by Nitrobacter bacteria. These nitrates can then be taken up by plants as a source of nitrogen for growth.
Where did saltpeter come from?
Saltpeter is a salt produced by the solution of nitrates with potassium. It is a naturally occurring deposit known as niter. It can also be produced in a laboratory.
How does nitrogen in the air and the soil converted into nitrates?
Nitrogen gas in the air is converted into nitrates through a process called nitrogen fixation by specialized bacteria. In the soil, nitrates are produced through nitrification, a two-step process involving the conversion of ammonium to nitrites and then to nitrates by bacteria.
What can produce nitrogen (ll) oxide?
Nitrogen(II) oxide can be produced by oxidation of NO, dehydration of HNO3, thermal decomposition of nitrates etc.
How would you use nitrates in a sentence?
nitrates are chemically salts. nitrates Can be used as fertilizers.

What are most nitrates?
Nitrates are ionic compounds soluble in water.

Does kosher meat have nitrates?
No ______ Kosher deli meat still has nitrates.
