Cut brinjal into small pieces.Take some pieces in a beaker with a little amount of water and boil it to prepare a brinjal extract.Now filter and collect this brinjal extract.
Tests:
(1)Add dil. sulphuric acid and ferrous sulphate to the extract.A brown solution will be formed. (1.1)To the solution formed, add few drops of conc.sulphuric acid by the wall of test tube.A brown ring will be formed.
(1.2)Add the solution formed in (1) in potassium permangnate(purple).Its colour fades.

What is the confirmatory test or nitrite anion?
The confirmatory test for the nitrite anion involves the Griess test, which detects the presence of nitrite ions in a sample by forming a deep red color complex with sulfanilic acid and N-(1-naphthyl)ethylenediamine dihydrochloride. This test is commonly used in the detection of nitrite in water, food, and biological samples.
What bacteria convert ammonia ions to nitrate ions?
Nitrosomonas bacteria are responsible for converting ammonia ions (NH4+) to nitrite ions (NO2-), while Nitrobacter bacteria further convert nitrite ions to nitrate ions (NO3-). This process is known as nitrification and is an important step in the nitrogen cycle.
If ammonium ions are converted to nitrate and nitrite to ions through which process?
The conversion of ammonium ions to nitrate is called nitrification, which is a two-step process involving the bacteria Nitrosomonas and Nitrobacter. The conversion of nitrite ions to nitrate is also part of the nitrification process.
What is Cr NO2 2?
Cr(NO2)2 is the chemical formula for chromium (II) nitrite, which is a compound formed by the combination of chromium with nitrite ions. It is a blue-green solid that is not commonly encountered in everyday situations.
Nitrate ions and nitrite ions are converted into nitrous oxide gas and nitrogen gas?
Yes, nitrate ions (NO3-) can be converted into nitrite ions (NO2-) through a process called denitrification, and both nitrate and nitrite ions can be further converted into nitrous oxide (N2O) and nitrogen gas (N2) through microbial processes in the environment. This transformation is part of the nitrogen cycle, where different forms of nitrogen are interconverted by microorganisms to maintain ecological balance.
How do you test for presence of nitrite ion?
To test for the presence of nitrite ions, you can use the Griess test. This involves adding sulfanilic acid and N-1-naphthylethylenediamine dihydrochloride to the solution containing nitrite ions, which will produce a pink color if nitrite ions are present. Another method is using a diphenylamine reagent, which will turn blue in the presence of nitrite ions.
What is the formula for nitrite ions?
Nitrite: NO2-
Is the solution of sodium nitrite acidic or basic?
Sodium nitrite is a basic compound. When dissolved in water, it forms a solution that is slightly basic due to the presence of the nitrite ion, which can accept protons and increase the concentration of hydroxide ions.
Does nitrite form nitrate?
Nitrite ions can form nitrate ions by reacting with oxidizing agents such as the oxygen in air.
What happens when sodium nitrite dissolves in water?
When sodium nitrite dissolves in water, it dissociates into its ions, forming sodium ions (Na+) and nitrite ions (NO2-). These ions are then surrounded by water molecules through hydration, resulting in a homogeneous solution. Sodium nitrite is commonly used in food preservation to inhibit the growth of bacteria and to give a pink color to meats like hot dogs and bacon.
Is lead nitrite a salt?
Lead nitrite is an ionic compound all of which are considered salts.
What reagents are used to confirm Ba plus 2?
To confirm the presence of Ba2+ ions, you can use a sulfate ion-containing solution, such as sulfuric acid (H2SO4), to form a white precipitate of barium sulfate (BaSO4). This precipitate is insoluble in water and confirms the presence of Ba2+ ions in the solution.
What is the confirmatory test or nitrite anion?
The confirmatory test for the nitrite anion involves the Griess test, which detects the presence of nitrite ions in a sample by forming a deep red color complex with sulfanilic acid and N-(1-naphthyl)ethylenediamine dihydrochloride. This test is commonly used in the detection of nitrite in water, food, and biological samples.
What happens when you put sodium nitrite in water?
When sodium nitrite is added to water, it dissociates into sodium ions (Na+) and nitrite ions (NO2-). The solution may also become slightly acidic due to the hydrolysis of nitrite ions. Sodium nitrite in water can also react with other compounds to form nitric oxide, which can be toxic in high concentrations.
What bacteria convert ammonia ions to nitrate ions?
Nitrosomonas bacteria are responsible for converting ammonia ions (NH4+) to nitrite ions (NO2-), while Nitrobacter bacteria further convert nitrite ions to nitrate ions (NO3-). This process is known as nitrification and is an important step in the nitrogen cycle.
What is the formula for arsenic III nitrite?
The formula for arsenic III nitrite is As(NO2)3. It represents one arsenic atom bonded to three nitrite ions.
What is Ga NO2 3?
Gallium nitrite (Ga(NO2)3) is a compound formed by the elements gallium and nitrite ions. It is a nitrite salt of gallium, where gallium has a +3 oxidation state. Gallium nitrite is a crystalline solid that is not commonly found in nature.
