Nitric acid, also known as aqua fortis and spirit of niter, is a highly corrosive strong mineral acid. The pure compound is colorless, but older samples tend to acquire a yellow cast due to decomposition into oxides of nitrogen and water. Formula: HNO3, Density: 1.51 gcm, Molar mass: 63.01 gmol, Boiling point: 83 C, IUPAC ID: Nitric acid, Melting point: -42 C Uses : Nitric acid in a laboratory. The main use of nitric acid is for the production of fertilizers. Nitric acid is neutralized with ammonia to give ammonium nitrate. This application consumes 7580% of the 26M tons produced annually (1987). The other main applications are for the production of explosives, nylon precursors, and specialty organic compounds.

Stearic acid is the saturated fatty acid with an 18-carbon chain and has the iupac name octadecanoic acid. It is a waxy solid, and its chemical formula is ch3(ch2)16co2h. Its name comes from the greek word "star", which means tallow. Formula: c18h36o2, density: 847.00 kgm, molar mass: 284.4772 gmol, boiling point: 376.1 c uses in general, applications of stearic acid exploit its bifunctional character, with a polar head group that can be attached to metal cations and a nonpolar chain that confers solubility in organic solvents. The combination leads to uses as a surfactant and softening agent. Stearic acid undergoes the typical reactions of saturated carboxylic acids, a notable one being reduction to stearyl alcohol, and esterification with a range of alcohols. Soaps, cosmetics, detergents stearic acid is mainly used in the production of detergents, soaps, and cosmetics such as shampoos and shaving cream products.

Sulfuric acid is a highly corrosive strong mineral acid with the molecular formula H2SO4. It is pungent-ethereal, colorless to slightly yellow viscous liquid which is soluble in water at all concentrations. Formula: H2SO4, Density: 1.84 gcm, Melting point: 10 C, Molar mass: 98.079 gmol, IUPAC ID: Sulfuric acid, Boiling point: 337 C, Classification: Sulfuric acids

Formic acid formic acid is the simplest carboxylic acid. Its chemical formula is hcooh or hco2h. It is an important intermediate in chemical synthesis and occurs naturally, most notably in ant venom. Formula: ch2o2, iupac id: formic acid, density: 1.22 gcm, boiling point: 100.8 c, molar mass: 46.02538 gmol, melting point: 8.4 c uses a major use of formic acid is as a preservative and antibacterial agent in livestock feed. In europe, it is applied on silage (including fresh hay) to promote the fermentation of lactic acid and to suppress the formation of butyric acid; it also allows fermentation to occur quickly, and at a lower temperature, reducing the loss of nutritional value. F formic acid is also significantly used in the production of leather, including tanning (23% of the global consumption in 2009), and in dyeing and finishing of textile (9% of the global consumption in 2009) because of its acidic nature. Use as a coagulant in the production of rubber constituted in 2009 6% of the global consumption. Formic acid is also used in place of mineral acids for various cleaning products, such as limescale remover and toilet bowl cleaner. Some formate esters are artificial flavorings or perfumes. Beekeepers use formic acid as a miticide against the tracheal mite (acarapis woodi) and the varroa mite.the use of formic acid in fuel cells is also under investigation.
