Sulphanillic Acid is a kind of white to off-white cystalline. It's hydrate loses moisture
at 100 ℃, and anhydrous carbide begins to decompose at 280 ℃.
Sulphanillic Acid slightly soluble in cold water, insoluble in ethanol, ether and benzene,
soluble in sodium hydroxide solution and sodium carbonate solution.
Sulphanillic Acid has a very significant acidity.
Content of aniline
Insoluble substance in water
Dissolved state in aqueous sodium carbonate
It is white powder and turns into white crystal when it absorbs water in the air and attaches one molcular of crystal water. The crystal water will be lost when the temperature reaches 100℃.
