Explanation
Butylated hydroxy toluene (BHT) is an antioxidant .Hence it used as an antioxidant food additive.
Aspartame is an artificial, non–saccharide sweetener used as a sugar substitute in some foods and beverages. Aspartame is a methyl ester of the aspartic acid/phenylalanine dipeptide.
Vat dyes are insoluble in water and cannot dye fibers directly. However, they can be made soluble by reduction in alkaline solution which allows them to affix to the textile fibers. Subsequent oxidation or exposure to air restores the dye to its insoluble form. Indigo is the original vat dye. These dyes are the fastest dyes for cotton, linen and rayon. They are used with mordant to dye other fabrics such as wool, nylon, polyesters, acrylics etc,.
Therefore Vat dyes are not used to dye nylon and polyesters.
Soaps can be classified as a salt of fatty acids
Bithional is an antiseptic which is generally added to medicated soaps to reduce the odour produced by bacterial decomposition of organic matter on the skin.
Soaps can be classified as a salt of fatty acids.
Soaps are water soluble sodium or potassium salts of fatty acids. Soaps are made from fats or oils, or their fatty acids by treating them chemically with a strong alkali having molecular formula.
C17H35COOK (potassium stearate).
Nitric acid (HNO3) is used as an oxidizer in rocket fuel.
Hydrogen peroxide is known to react with silver but for this it has to be highly concentrated- near about 90%. This is much higher than the hydrogen peroxide sold at the drug store which has concentration of only 3%. The highly concentrated 90% hydrogen peroxide has to be strictly stored in special 5254 aluminum alloy containers having vented caps arranged in shaded ventilated rooms. Hydrogen peroxide with such high concentration can be used as a rocket propellant. Its chemical formula is H2O2. The moment silver and hydrogen peroxide comes in contact, silver starts acting as a catalyst. Due to this reaction the extra oxygen atom is freed producing water as the byproduct. This also creates immense heat. The heat thus produced transforms the water into steam which is used by the engine for ejection at huge speed via rocket nozzle.
Heroin is prescribed as an analgeric, cough suppresant and as an antidiarrhoeat. It is not a tranquilliser
