A nitrate test is a chemical test used to determine the presence of nitrate ion in solution. Testing for the presence of nitrate via wet chemistry is generally...

the nitrate ion, which forms the same complex in a ring. In contrast, nitrites turn the whole solution brown and therefore interfere with that test. A...

The nitrate reductase test is a test to differentiate between bacteria based on their ability or inability to reduce nitrate (NO3−) to nitrite (NO2−) using...

(anaerobic growth), it is capable of nitrate reduction under anoxic conditions. Therefore, nitrate tests are positive since nitrate is generally used as the final...

Silver nitrate is an inorganic compound with chemical formula AgNO 3. It is a versatile precursor to many other silver compounds, such as those used in...

industry tends to use nitrate-based explosives such as emulsions of fuel oil and ammonium nitrate solutions, mixtures of ammonium nitrate prills (fertilizer...

Hydroxylammonium nitrate or hydroxylamine nitrate (HAN) is an inorganic compound with the chemical formula [NH3OH]+[NO3]−. It is a salt derived from hydroxylamine...

High-test peroxide (HTP) is a highly concentrated (85 to 98%) solution of hydrogen peroxide, with the remainder consisting predominantly of water. In contact...

Ceric ammonium nitrate (CAN) is the inorganic compound with the formula (NH4)2[Ce(NO3)6]. This orange-red, water-soluble cerium salt is a specialised...

Nitrate reductases are molybdoenzymes that reduce nitrate (NO− 3) to nitrite (NO− 2). This reaction is critical for the production of protein in most...
