Answer:
One procedure is for 4-nitroaniline. The other procedure is for the sulfonic acid substituted anilines. The azo dye will be used to dye a piece of fabric using the direct dyeing process. Direct dyeing is achieved by treating a fabric with a diazo component and a coupling component to make an insoluble azo dye.
