Nitric acid is an inorganic compound with the formula H N O 3. It is a highly corrosive mineral acid. [6] . The compound is colorless, but samples tend to acquire a yellow cast over time due to decomposition into oxides of nitrogen. Most commercially available nitric acid has a concentration of 68% in water.

Nitric acid is a nitrogen oxoacid of formula HNO3 in which the nitrogen atom is bonded to a hydroxy group and by equivalent bonds to the remaining two oxygen atoms. It has a role as a protic solvent and a reagent. It is a conjugate acid of a nitrate.

2012年9月19日 · Nitric acid obtained in laboratory is slightly yellow due to the dissolution of nitrogen dioxide which is produced due to thermal decomposition of a portion of $\ce {HNO3}$. $$ \ce {4HNO3 -> 2...

2025年1月27日 · Nitricacid,HN03, is a strong,fire-hazardous oxidant. It is a colorless or yellowish liquid that is miscible with water and boils at 86℃ (187 ℉). Nitric acid, also known as aqua fortis, is used for chemical synthesis, explosives, and fertilizer manufacture, and in metallurgy, etching, engraving, and ore flotation.

Nitric Acid is a inorganic compound with chemical formula HNO3. It is a highly corrosive mineral acid, fuming, colourless and plays a important role in the manufacture of fertilisers and explosives. It is also known as the spirit of niter and aqua fortis. In its pure form, it is colourless but as it gets older it turns into a yellow cast.

2024年4月22日 · Nitric acid HNO 3, is a viscous, odorless, colorless liquid, in pure form, but brownish yellow in color, due to dissolved nitrogen oxide impurities. It releases yellow fumes (hence its name fuming acid) at room temperature. It is soluble in water and has a melting point of -41.6 ºC, and a boiling point of 83 ºC.

Color of nitrogen dioxide is brown. Due to this dissolved nitrogen dioxide conc. nitric acid (HNO 3) is brownish red in color. Pure anhydrous nitric acid (100%) is a colorless mobile liquid with a density of 1.512 g/cm3 which solidifies at –42°C to form white crystals and boils at 83°C.

2023年12月4日 · Nitric Acid is a powerful and highly corrosive acid with the chemical formula HNO3. Nitric Acid is a colorless liquid that can range from pale yellow to reddish-brown due to decomposition into nitrogen dioxide and water.

Nitric acid is a chemical compound that has a chemical formula HNO 3. It is a mineral acid that's quite corrosive. Nitric acid in its purest form is colorless. When the heat is absorbed, it becomes extremely unstable. Nitrogen dioxide (NO 2) is produced when …

Nitric acid, upon exposure to light and heat, will spontaneously decompose to nitrogen dioxide, water, and oxygen, creating the brownish-yellow color.It's not actually completely decomposing unless you leave it for a long time but there's enough dissolved nitrogen dioxide, which is what imparts the color, to give it a distinct yellowish brown ...
