Character of Indigo

 

 

Indigo is a blue powder, soluble in hot aniline, almost insoluble in water and ethanol. It is yellow-green in concentrated sulphuric acid and diluted as a blue precipitate; it is indigo-red in concentrated nitric acid and then turns reddish yellow. It is pale yellow in alkaline insurance powder reducing solution and colourless in acidic solution.

Indigo is insoluble in water, acid and alkali, and to be made into a dyeing solution to adsorb fabric, it must first undergo reduction and become indigo white. Indigo white is soluble in alkaline solution and can be used to colour animal or vegetable fibres, which are oxidised in the air after dyeing to produce indigo blue again, which adheres to the fibres and is blue. Therefore the dyeing solution for indigo must have a reducing agent and a lye solution present.
