[edit] Distillation

Striking comments carried over from the previous peer review, used for testing.This article was the Wikipedia:Chemistry Collaboration of the Month for Nov 2006. The article has went through quite a few revisions since. From a scientific point of view, it does cover the important parts. The field is too broad for the article to be exhaustive. How about from a non-technical point of view? Tone? Style? Examples? Pictures? Please comment! --Rifleman 82 22:51, 1 December 2006 (UTC)

I think that some plots depicting Raoult's law would be very helpful, if not here, then certainly in the article about Raoult's law. Itub 14:19, 5 February 2007 (UTC)

How about this image?It assumes an idealized situation at 20 C - no deviation from Raoult's law. Data taken from http://www.jtbaker.com/msds/englishhtml/h2381.htm and http://www.jtbaker.com/msds/englishhtml/h0584.htm. If this graph is okay, I can fix the aesthetics later. --Rifleman 82 16:57, 5 February 2007 (UTC)

I think the kinds of plots used in http://www-jcsu.jesus.cam.ac.uk/~rpc25/notes/chemistry/phase_equillibria/index.html are more illustrative, because they show how the total vapor pressure results from the sum of the vapor pressure of each component (each one being proportional to its mole fraction). This site also shows examples with deviations from Raoult's law, and the plots near the bottom of the page show how fractional distillation works, and why it doesn't work when azeotropes are formed. --Itub 11:27, 7 February 2007 (UTC)

Another topic that might be good to mention in the article is the "lever rule". I'm actually surprised to find out that there's no wikipedia article on that topic yet! --Itub 11:30, 7 February 2007 (UTC)

[edit] Automated review

The following suggestions were generated by a semi-automatic javascript program, and might not be applicable for the article in question.

• Please expand the lead to conform with guidelines at Wikipedia:Lead. The article should have an appropriate number of paragraphs as is shown on WP:LEAD, and should adequately summarize the article.^[?]

*There may be an applicable infobox for this article. For example, see Template:Infobox Biography, Template:Infobox School, or Template:Infobox City.^[?] (Note that there might not be an applicable infobox; remember that these suggestions are not generated manually) - not applicable Rifleman 82 08:20, 11 February 2007 (UTC)

• Per Wikipedia:Manual of Style (numbers), there should be a non-breaking space -   between a number and the unit of measurement. For example, instead of 60 meters, use 60 meters, which when you are editing the page, should look like: 60 meters.^[?]

*Per Wikipedia:Manual of Style (headings), headings generally do not start with articles ('the', 'a(n)'). For example, if there was a section called ==The Biography==, it should be changed to ==Biography==.^[?]

• Per Wikipedia:Manual of Style (headings), headings generally should not repeat the title of the article. For example, if the article was Ferdinand Magellan, instead of using the heading ==Magellan's journey==, use ==Journey==.^[?] done --Rifleman 82 08:20, 11 February 2007 (UTC)
• Watch for redundancies that make the article too wordy instead of being crisp and concise. (You may wish to try Tony1's redundancy exercises.)
  • Vague terms of size often are unnecessary and redundant - “some”, “a variety/number/majority of”, “several”, “a few”, “many”, “any”, and “all”. For example, “All pigs are pink, so we thought of a number of ways to turn them green.”
• Please ensure that the article has gone through a thorough copyediting so that it exemplifies some of Wikipedia's best work. See also User:Tony1/How to satisfy Criterion 1a.^[?]
