Mention any two chemical inventedduring the
Industrial Revolution
Answers
Explanation:
One of the first chemicals to be produced in large amounts through industrial processes was sulfuric acid. In 1736, the pharmacist Joshua Ward developed a process for its production that involved heating saltpeter, allowing the sulfur to oxidize and combine with water.
Answer:
The large scale production of chemicals was an important development during the Industrial Revolution. The first of these was the production of sulfuric acid by the lead chamber process invented by the Englishman John Roebuck in 1746. He was able to greatly increase the scale of the manufacture by replacing the relatively expensive glass vessels formerly used with larger, less expensive chambers made of riveted sheets of lead. Instead of a few pounds at a time, he was able to make a hundred pounds (45 kg) or so at a time in each of the chambers.
The production of an alkali on a large scale became an important goal as well, and Nicolas Leblanc succeeded in 1791 in introducing a method for the production of sodium carbonate. The Leblanc process was a reaction of sulfuric acid with sodium chloride to give sodium sulfate and hydrochloric acid. The sodium sulfate was heated with limestone (calcium carbonate) and coal to give a mixture of sodium carbonate and calcium sulfide. Adding water separated the soluble sodium carbonate from the calcium sulfide. The process produced a large amount of pollution (the hydrochloric acid was initially vented to the air, and calcium sulfide was a useless waste product) but proved economical over the previous method of deriving it from wood ashes, barilla, or kelp.
These two chemicals were very important because they enabled the introduction of a host of other inventions, replacing many small-scale operations with more cost-effective and controllable processes. Sodium carbonate had many uses in the glass, textile, soap, and paper industries. Early uses for sulfuric acid included pickling (removing rust) iron and steel, and for bleaching cloth.
