No, it doesn't.
The substrate for nitrate reductase is nitrate (NO3-). Nitrate reductase catalyzes the reduction of nitrate to nitrite (NO2-) during the process of nitrate assimilation in plants and microorganisms.
KNO3 is the chemical formula of potassium nitrate.
The symbol for nitrate is NO3-. The valency of nitrate is -1.
Potassium nitrate is KNO3. There is one potassium per one nitrate. One mole of potassium nitrate contains one mole of nitrate.
Tetrachloroethylene is not a nitrate.
Nitrate: NO3-
amyl nitrate
For example in nitrates as: sodium nitrate, potassium nitrate, uranyl nitrate, ammonium nitrate, etc.
When sodium nitrate and silver nitrate are mixed, no reaction occurs. These compounds do not react with each other to form a new compound. Sodium nitrate remains as sodium nitrate and silver nitrate remains as silver nitrate when they are mixed together.
Potassium Nitrate has the formula KNO3. Patassium Nitrate is a typo.
copper nitrate is also called as cupric nitrate
