In 1803, Dalton summarized his observations in this statement: For a mixture of gases in a container, the total pressure exerted is the sum of the pressures that each gas would exert if it were alone. This statement, known as Dalton's law of partial pressures, can be expressed as follows: Ptotal = P1 + P2 + P3 + …, where the subscripts refer to the individual gases (gas 1, gas 2, etc.). P1, P2, P3, are called partial pressures. |
