Further, natural dyes tended to be muddy in hue and fade quickly. 7 TRUEFALSENOT GIVEN    Perkin was inspired by the discoveries of the famous scientist Louis Pasteur. William Henry Perkin was born on March 12, 1838, in London, England. William Henry Perkin was born on March 12,1838, in London, England. Artificial dyes continue to play a crucial role today. And, proving the truth of the famous scientist Louis Pasteur’s words ‘chance favours only the prepared mind’, Perkin saw the potential of his unexpected find. During his vacation in 1856, Perkin spent his time in the laboratory on the top floor of his family’s house. As a student at the City of London School, Perkin became immersed in the study of chemistry. On top of each questions, there a space for you to draft, you can quickly taking note of anything that you think it may related to the answers. 8    Before Perkin’s discovery, with what group in society was the colour purple associated?8, 9    What potential did Perkin immediately understand that his new dye had?9, 10    What was the name finally used to refer to the first colour Perkin invented?10, 11    What was the name of the person Perkin consulted before setting up his own dye works?11, 12    In what country did Perkin’s newly invented colour first become fashionable?12, 13    According to the passage, which disease is now being targeted by researchers using synthetic dyes?13. At the time of Perkin’s enrolment, the Royal College of Chemistry was headed by the noted German chemist August Wilhelm Hofmann. It was against this backdrop that Perkin’s discovery was made. William Henry Perkin was born on March 12,1838, in London, England. He was attempting to manufacture quinine from aniline, an inexpensive and readily available coal tar waste product. Perkin quickly grasped that his purple solution could be used to colour fabric, thus making it the world’s first synthetic dye. But it was a chance stumbling upon a run-down, yet functional, laboratory in his late grandfather’s home that solidified the young man’s enthusiasm for chemistry. 3 TRUEFALSENOT GIVEN    Perkin employed August Wilhelm Hofmann as his assistant. 5 TRUEFALSENOT GIVEN    The trees from which quinine is derived grow only in South America. But perhaps the most fascinating of all Perkin’s reactions to his find was his nearly instant recognition that the new dye had commercial possibilities. Not long after that, Perkin made the scientific breakthrough that would bring him both fame and fortune. TRUE    if the statement agrees with the information, FALSE    if the statement contradicts the information, NOT GIVEN    if there is no information on this. Perkin went back to the drawing board. At the time, quinine was the only viable medical treatment for malaria. Do the following statements agree with the information given in Reading Passage? 2 TRUEFALSENOT GIVEN    Michael Faraday suggested Perkin should enrol in the Royal College of Chemistry. Not to be outdone, England’s Queen Victoria also appeared in public wearing a mauve gown, thus making it all the rage in England as well. Remember to transfer them to the answer boxes. 6 TRUEFALSENOT GIVEN    Perkin hoped to manufacture a drug from a coal tar waste product. Although Perkin’s fame was achieved and fortune assured by his first discovery, the chemist continued his research. Despite his best efforts, however, he did not end up with quinine. But it was a chance stumbling upon a run-down, yet functional, laboratory in his late grandfather's home that solidified the young man`s enthusiasm for chemistry. Among other dyes he developed and introduced were aniline red (1859) and aniline black (1863) and, in the late 1860s, Perkin’s green. His talent and devotion to the subject were perceived by his teacher, Thomas Hall, who encouraged him to attend a series of lectures given by the eminent scientist Michael Faraday at the Royal Institution. As a boy, Perkin’s curiosity prompted early interests in the arts, sciences, photography, and engineering. But it was a chance stumbling upon a run-down, yet functional, laboratory in his late grandfather’s home that solidified the young man’s enthusiasm for chemistry. Read the passage below and answer questions 1 – 13. For instance, they were used to stain previously invisible microbes and bacteria, allowing researchers to identify such bacilli as tuberculosis, cholera, and anthrax. And, in what would have been particularly pleasing to Perkin, their current use is in the search for a vaccine against malaria. Historically, textile dyes were made from such natural sources as plants and animal excretions. Incorporating potassium dichromate and alcohol into the aniline at various stages of the experimental process, he finally produced a deep purple solution. * This window is to review your answers only, you cannot change the answers in here. Perkin’s scientific gifts soon caught Hofmann’s attention and, within two years, he became Hofmann’s youngest assistant.
