Talk:Contact process

Every textbook I've ever read has referred to the Contact Process as just the reversible reaction producing sulphur trioxide from sulphur dioxide and oxygen, not the entire process of the production of sulphur. I know article kind of gets this across, but the first line, "The contact process is the current method of producing sulphuric acid in the high concentrations needed for industrial processes" is misleading. Perhaps a re-write is in order here. Liverpool Scouse 11:31, 9 December 2006 (UTC)

The standard for spelling of sulfur in science article is sulfur.

:In the interest of consistency and clarity the IUPAC standard should be used for chemical names in all science articles. Alternative spellings should be referenced in addition, especially when dealing with regional issues and historical development.

:*The IUPAC currently recommends:

:*Aluminium instead of aluminum

:*Caesium instead of cesium

:*Sulfur instead of sulphur

Hey, I was never good at chem, but every textbook I have read says that a catalyst does not change the position of equilibrium. But the article says "A catalyst is necessary for this reaction or the equilibrium of the reaction would move to the left, producing more SO2." I think this is wrong, but just to make sure, I am posting this in discussions. —The preceding unsigned comment was added by 203.199.207.3 (talk) 16:49, 7 April 2007 (UTC).

I've added a {{contradict}} tag because the article can't seem to decide if Vanadium or Platinum is used as the catalyst, and which is poisoned by impurities. MrBell ^(talk) 17:40, 18 January 2010 (UTC)

The following publication shows that vanadium does not undergo a change in oxidation state in this process. The German Wikipedia shows the graphic to the catalytic cycle as found by Lapina et al.

Could anyone please correct it?

Hello fellow Wikipedians,

I have just added archive links to {{plural:1|one external link|1 external links}} on Contact process. Please take a moment to review [https://en.wikipedia.org/w/index.php?diff=prev&oldid=712475569 my edit]. You may add {{tlx|cbignore}} after the link to keep me from modifying it, if I keep adding bad data, but formatting bugs should be reported instead. Alternatively, you can add {{tlx|nobots|deny{{=}}InternetArchiveBot}} to keep me off the page altogether, but should be used as a last resort. I made the following changes:

• Added archive http://web.archive.org/web/20100523153700/http://www.ravensdown.co.nz/Resources/Education/History.htm to http://www.ravensdown.co.nz/Resources/Education/History.htm

When you have finished reviewing my changes, please set the checked parameter below to true or failed to let others know (documentation at {{tlx|Sourcecheck}}).

{{sourcecheck|checked=false}}
