Deviations from Raoult's Law [edit]

Can someone provide information on how activity coefficients demonstrate either positive or negative deviations from Raoult's Law? 171.64.133.56 22:53, 24 February 2006 (UTC)

Henry's law is actually the relation between partial pressure of the gases and the solubility of the gases at a given temperature. It defines that the solubility of a gas is directly proportional to the partial pressure of the gas. If we remove the proportionality sign then we insert a constant that constant is called the Henry's law constant.

Lead paragraph [edit]

This article needs a lead paragraph that introduces the subject, any practical "real world" applications and does so in layman's terms before launching into the technical explanation. Anyone want to try? --Monotonehell 04:11, 17 March 2007 (UTC)

application of raoult`s law [edit]

applications of rault`s law may be found as colligative properties.root cause of all such properties is vapor pressure which is explained in Raoult`s law

proof of roult's law [edit]

What is the proof of the law that vapour pressure of a component of a solution is V.P. of its pure form multiplied by its mole fraction in the solution? —Preceding unsigned comment added by 121.247.78.162 (talk) 05:29, 11 October 2009 (UTC)

Positive deviation diagram is incorrect??? [edit]

Should there not be a green curve, as in the negative deviation diagram but, bulging upwards that sums up the individual vapor pressures? LoneSeeker (talk) 16:12, 30 December 2009 (UTC)

Diagrams should be more general [edit]

All three diagrams (ideal and non-ideal) assume that the vapour pressures of the two pure components are equal: pA* = pB*, so that the total vapour pressure is independent of the mole fraction and is represented as a horizontal line. However this is only a special case - in general this assumption is not true and the total vapour pressure line should have a non-zero slope. More general diagrams can be found in most general chemistry and physical chemistry texts. Dirac66 (talk) 17:42, 9 November 2010 (UTC)

Done. I have now replaced these diagrams with new diagrams for which the Raoult's law total vapor pressure has a non-zero slope. The new diagrams are copied from the Italian Wikipedia and I have re-captioned them in English. Dirac66 (talk) 01:07, 27 May 2012 (UTC)

Electrolytes [edit]

The statement for electrolytes should be added.--82.137.12.0 (talk) 23:32, 9 August 2012 (UTC)
