John Dalton

summary and experiment

Chemist John Dalton was born September 6, 1766, in Eaglesfield, England. During his early career, he identified the nature of red-green color blindness. In 1803 he revealed the concept of Dalton’s Law of Partial Pressures, in the 1800s, he was the first scientist to explain the behavior of atoms in of the measurement of weight. Dalton died July 26, 1844 in Manchester, England.

Dalton's experiments on gases led to his discovery that the total pressure of a mixture of gases amounted to the sum of the partial pressures that each individual gas exerted while occupying the same space. In 1803 this scientific principle officially came to be known as Dalton's Law of Partial Pressures. Dalton's Law primarily applies to ideal gases rather than real gases, due to the elasticity and low particle volume of molecules in ideal gases.
