Sulfanilic acid (4-aminobenzene sulfonic acid) is a colourless crystalline solid produced from sulfonation of aniline. The melting point of a solid is the temperature range at which it changes state from solid to Liquid. Solubility is the characteristic Physical property referring to the ability of a given substance the Solute, to dissolve in a Solvent. Water is a common Chemical substance that is essential for the survival of all known forms of Life. In Chemistry, the standard state of a material is its state at 1 bar (100 Kilopascals exactly Aromatic sulfonation is an Organic reaction in which a hydrogen atom on an arene is replaced by a Sulfonic acid Functional group in an Electrophilic Aniline, phenylamine or aminobenzene is an Organic compound with the formula C6H7N [1]
It readily forms diazo compounds and is used to make dyes and sulpha drugs. Diazo refers to a type of Organic compound that has two linked nitrogen (azo compounds There are several sulfonamide-based groups of drugs The original antibacterial sulfonamides (sometimes called simply sulfa drugs are synthetic antimicrobial agents that contain the sulfonamide [1]
Sulphanilic acid exists as a zwitterion, and has an unusually high melting point. A zwitterion (first part pronounced "tsvitter" from German " Zwitter " &mdash "hybrid" " Hermaphrodite " is a The melting point of a solid is the temperature range at which it changes state from solid to Liquid.
