Question
Which scientist first prepared the Hydrogen gas?
- J.J. Thomson
- Robert Boyle
- Henry Cavendish
- Lavoisier
Hint:
The scientist thought it to be ordinary gas and ignored it.
The correct answer is: Robert Boyle
The correct option is b) Robert Boyle.
- Robert Boyle produced hydrogen gas in 1671 during his iron and acid experiments.
- Robert Boyle discovered and described that the reaction of scrap iron with dilute acid resulted in the production of hydrogen gas.
- Between 1766 and his 1781, Henry Cavendish was the first to recognize that hydrogen gas is itself a substance, which when burned produces water. He called it "flammable air."
