Methods/Materials: 7.1 Experiment: Rate of Diffusion of Solutes In the initial set up of this experiment I had 2 sets of 3 screw-cap test tubes that had each been half-filled with 5% gelatin and 1-mL of the correct dye (either potassium dichromate‚ aniline blue‚ or Janus green) in each of the test tubes. I labeled the 3 test tubes of set 1 with which die they contained and marked them “5 ˚C”. Then with the other set I did the same exact thing‚ except I labeled these test tubes “Room Temperature”. I

Du Pont uses only a small number of hazardous substances – such as lead‚ aniline‚ and orthotoluidine – that require special control. Over the years‚ the company has promulgated several policies dealing with reproductive hazards‚ particularly one that addressed the problem of fetal damage from chemical exposure.

Natural dyes are dyes or colorants derived from plants‚ invertebrates‚a or minerals. The majority of natural dyes are vegetable dyes from plant sources – roots‚ berries‚ bark‚ leaves‚ and wood — and other organic sources such as fungi and lichens. Archaeologists have found evidence of textile dyeing dating back to the Neolithic period. In China‚ dyeing with plants‚ barks and insects has been traced back more than 5‚000 years.[1] The essential process of dyeing changed little over time. Typically
