Looks like a dicdef? Should it be moved to Wikitionary? Krik 23:04, 26 May 2004 (UTC)
- It would probably be fine if there was more scientific description and more examples, going into detail. In other words: It's a stub. Gadriel 03:58, Nov 15, 2004 (UTC)
- Looks like it has expanded enough to make this obsolete.RJFJR 23:49, 11 October 2005 (UTC)
This is kind of a mouth full:
Can we find a simpler example? RJFJR 23:49, 11 October 2005 (UTC)
How is this different from Miscibility?
--Scott 19:43, 27 April 2006 (UTC)
- Good question. DMacks 16:58, 16 May 2006 (UTC)
Fails to fully address temperature dependence of miscibility. Component fluids (e.g., oil and water) may become completely miscible at a high enough temperature called the "consolute point." The mixture exhibits interesting critical behavior at the consolute point. This is not mentioned. — Preceding unsigned comment added by Rcruise (talk • contribs) 13:47, 13 December 2012 (UTC)
Currently, this page is in Category:Chemical properties. However, to my knowledge, miscibility is a physical property. It appears that Category:Physical properties would not be appropriate. That being said, shouldn't the page be removed from the current category (and ideally, moved to a more appropriate one)? PaplooTheEwok (talk) 03:07, 2 February 2013 (UTC)
Butanone - why?
Not a SME, but I wonder why butanone was the chosen example. Wouldn't Sodium Chloride be equally acceptable, since its the best known (chemically) solid material known to mankind? Bcwilmot 08:14, 21 October 2014 (UTC)
Metal Behavior (Mott #)
This is a quote from the abstract of 'Immiscibilty in Liquid Metal Systems', JMS, 1968, available at http://link.springer.com/article/10.1007/BF00550987 as PDF. Depending on the detail desired, the Mott # math (claimed correct immiscibilty prediction of 85%) from the abstract, or further details from the paper could be included to give a quick way to say "are these two metals immiscible?" which is 1st order useful to a person reading about immiscible metals.
The original Hildebrand formula was based on a solubility parameter, δ, and the atomic volume, V, and immiscibility was predicted between two liquids if 1/2(V A+V B) (δ A−δ B)2>2RT
Mott introduced a correction term in this expression to allow for the difference in electronegativity (χ A−χ B) between the two component elements and defined a Mott number,
12(VA+VB) (δA−δB)2−2RT23060 (χA+χB)2, where T is the melting point, in degrees absolute, of the more refractory metal. It was postulated that if the calculated Mott number for a given binary alloy system was greater than the number of bonds that could be formed, the two metals would be immiscible in the liquid state. In an earlier paper, the Mott number was compared with the lower Pauling valency of the two elements and when this is applied to 1401 known alloy systems, the overall agreement is 85% compared with 59.9% conforming to the simple Hildebrand rule.
Miscibility and solubility?
There seems to be very little coordination between this topic and Solubility?
