The nitrous acid color test is also known as the Griess test. It is a chemical test used to detect the presence of compounds that contain nitrogen, such as nitrites or secondary amines, which form a colored complex when treated with nitrous acid.
Nitrous acid (preferred IUPAC name) or systematic name: Hydroxido-oxido-nitrogen (alternatively, but uncommon) formula HO-N=O
The acid with the formula HNO2 is called nitrous acid.
HNO3 is Nitric Acid Compare with HNO2 ; Nitrous Acid. Note the difference in the formulas and the names. Accounted for by the different oxidation states of nitrogen .
H2SO3 is SULPHUROUS ACID . Compare with H2SO4 is Sulphuric acid. Note the spelling/ The name is due to sulphur having a different oxidation number. Also compare with ;- Nitric Acid (HNO3) and nitrous acid (HNO2)
HONO2 is usually written as HNO3 , which is Nitric Acid.
Nitrous acid (preferred IUPAC name) or systematic name: Hydroxido-oxido-nitrogen (alternatively, but uncommon) formula HO-N=O
The common name of this compound is nitrous acid, and the systematic name is Nitric(III) Acid.
Sulphuric acid Nitric acid Sulphurous acid Nitrous acid
The acid with the formula HNO2 is called nitrous acid.
HNO3 is Nitric Acid Compare with HNO2 ; Nitrous Acid. Note the difference in the formulas and the names. Accounted for by the different oxidation states of nitrogen .
NO2 is the polyatomic ionic compound nitrite Since it is bonded with hydrogen, this compound is an acid The correct name for HNO2, is therefore nitrous acid
If you are referring to HNO2, then it's nitrous acid, but I'm not sure what HINO2 is.
SO2 or if it mixes with NO2 (nitrous oxide) it turns into acid rain
The acid with the formula HNO2 is nitrous acid.
H2SO3 is SULPHUROUS ACID . Compare with H2SO4 is Sulphuric acid. Note the spelling/ The name is due to sulphur having a different oxidation number. Also compare with ;- Nitric Acid (HNO3) and nitrous acid (HNO2)
The usual name is nitrous acid - HNO2.
HONO2 is usually written as HNO3 , which is Nitric Acid.
