Sulfuric acid or sulphuric acid, known in antiquity as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen and hydrogen, with the molecular formula H2SO4. It is a colorless, odorless and viscous liquid that is miscible with water.

The Ricca Chemical nitric acid with a composition of 88.13% water and 11.87% nitric acid, is suitable for use as a laboratory reagent. It plays a major role in manufacturing of plastics, dyes, and fertilizers. It can be stored at a temperature of 15 to 30 degree C.

Nitric acid is the inorganic compound with the formula HNO3. It is a highly corrosive mineral acid. The compound is colorless, but older samples tend to be yellow cast due to decomposition into oxides of nitrogen. Most commercially available nitric acid has a concentration of 68% in water.
