The quote from Louis Pasteur, "chance favors only the prepared mind," in the context of Perkin's discovery, suggests that:
Success is purely a matter of luck.
Preparation and knowledge increase the likelihood of making important discoveries.
Scientific breakthroughs are always planned and deliberate.
Only those who are highly educated can achieve success.
What was a major drawback of natural textile dyes before Perkin's discovery?
They were often muddy in hue and faded quickly.
They were inexpensive and easy to obtain.
They were too vibrant and long-lasting.
They were primarily derived from synthetic materials.
Why was the purple dye extracted from snails historically so expensive?
It was easy to produce in large quantities.
The extraction process was simple and quick.
The dye was difficult to obtain and required large amounts of snail mucus.
It was used only for painting.
What was William Henry Perkin’s significant realization about his purple solution?
It was not commercially viable.
It was the first dye that could not be patented.
It could be used to create new medicines.
It could be used to colour fabric, making it the world’s first synthetic dye.
What was the original name that Perkin gave to his dye?
Mauve
Tyrian Purple
Violet
Royal Purple
What concern did Robert Pullar emphasize when advising Perkin about manufacturing his dye?
The dye’s ease of production.
The dye’s ability to create a variety of colors.
The dye’s environmental impact.
The dye’s affordability and its ability to remain fast (not fade).
What event helped to popularize Perkin’s mauve dye in England?
Queen Victoria wearing a mauve gown in public.
A fashion show in Paris.
The discovery of a new dyeing technique.
A recommendation from his mentor, Hofmann.
Which of the following dyes was NOT developed by William Henry Perkin?
Aniline red
Aniline black
Perkin’s green
Tyrian purple
What significant impact did Perkin's synthetic dyes have beyond their use in textiles?
They were used to create perfumes.
They played a vital role in medical research, such as identifying microbes like tuberculosis and cholera.
They were used exclusively for royal garments.
They replaced natural dyes in food production.
