A methyl orange lab experiment was conducted where we made methyl orange through the typical diazotization. We then placed various fabrics( Polyester, Cotton, Silk, and Nylon) into the dye solution and then into a destained solution and recorded qualitative results. For example: Polyester had little to no color change. Silk turned very orange after reacting. Nylon also turned orange. Cotton changed to a light red/pink. IN DETAIL, please discuss the chemistry of the reaction of EACH FABRIC with DYE METHYL...
