Application of Dalton’s Law of Partial Pressure

(1).        Gases which don’t react with water are usually collected by downward displacement of water and is collected over the water. The pressure exerted by gas will not be only due to gas collected but also due to water vapours. The pressure due to water vapour is known as Aqueous Tension. Thus according to Dalton’s law of partial pressure,
Pmoist gas   =    Pdry gas     +   Pwater vapours
Pmoist gas   =    Pdry gas     +   aq.Tension
Pdry gas      =    Pmoist gas ─   aq.Tension

(2).         Calculation of Partial Pressure

  1. so lame...cant you make a list of at least 5 applications...? anyways, thanks for trying...no offense by the way.
