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.

Develops yellow color in the presence of light due to nitrogen oxide formation. Stains woolen fabrics and animal tissue a bright yellow; strong, monobasic acid; oxidizing agent. Reacts violently with combustible or readily oxidizable materials such as …

Sep 19, 2012 · 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 $\ce{HNO3}$. $$ \ce {4HNO3 -> 2H2O + 4NO2 + O2}$$

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.

Jan 27, 2025 · 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.

Dec 4, 2023 · 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.

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.

Apr 22, 2024 · 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: 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 is thermally decomposed. As a result of the dissolution of Nitrogen dioxide, nitric acid turns yellow. Hence, Nitric acid is …

TCC’s nitric acid (HNO 3), is a highly corrosive and toxic strong mineral acid that is normally colorless but tends to acquire a yellow cast to the accumulation of oxides of nitrogen if long–stored. Ordinary nitric acid has a concentration of 68%. When the solution contains more than 86% HNO3, it is referred to as fuming nitric acid.
