The solubility of mercury
« on: 14/07/2006 06:36:01 »
Does anyone know whether there exists any petroleum based liquid which is fully miscible with mercury, in proportions such that there is at least 5% of either liquid present?

Does anyone know whether there exists any substance which, when mixed with oil and mercury, will emulsify the mix in the manner of a detergent?

Does anyone know what happens when mercury is mixed with plumbic cloride (PbCl4)?

Making an emulsion of mercury in a pteroleum based liquid (or vice versa) will be very difficult because of the high density of mercury.  In an emulsion or a colloid interfacial tensions between the liquids must compensate for the differences in density, which would make the minuscule droplets either rise of decant.

The interatomic forces in mercury are very strong, it has a higher surface tension than water, where as petroleum based liquids are only hled together by Van der Waals forces so it is probably going to be hard work or involve some funky chemistry.

Do I want to ask why you are asking this?

To ascertain whether all liquids fall into either the aqueous or oleous class (or somewhere in between, as an alcohol), or whether there are yet other classes of liquids that are distinctly neither. It would appear, from what you say, that there is indeed at least one other class. One of the consequences is, of course that if so, then it is possible to have more than two mutually immiscable liquids together in a single container.

You can fill a container with methanol, salt water, mercury, decane and perfluorooctane, shake it and watch all 5 mutually immiscible liquids settle out.
