Passage Excerpt:
In 1856, eighteen-year-old chemist William Henry Perkin was attempting to synthesize quinine, a scarce drug used to treat malaria, in his makeshift home laboratory. During one of his failed trials, he ended up with a dark, sludge-like residue at the bottom of his flask. Rather than discarding the mess, Perkin cleaned the flask with alcohol and noticed that the substance dissolved into a brilliant, deep purple liquid. Recognizing the commercial potential of this accidental creation, he patented the substance as the world's first synthetic dye, mauveine.
Given that all the choices are true, which one most effectively highlights the contrast between the cheap, synthetic source of Perkin's new dye and the expensive, natural sources of traditional dyes?
- This accidental substance could easily be mass-produced from coal tar, unlike traditional dyes that required harvesting thousands of rare plants or insects.Cevap
- BPerkin cleaned the flask using industrial alcohol and observed a brilliant, deep purple liquid that did not fade when washed.
- CThis purple residue was synthesized from industrial waste, traditional dyes were extremely difficult to obtain.
- DPerkin went on to establish a factory to produce this synthetic dye, which soon became highly fashionable in Victorian England.
