can any one tell me how to dye mercury with red color
or how to prepare it ??? ???
thanks ;D
-
You mean red mercury as in terrorism, or red mercury as in cinnabar?
-
hmm... I think he actually means in thermometres. It's not actually mercury if it's red, but I remember some of the teachers trying to teach me it was in school ::)
Mercury oxide can also be red... please elaborate, temp.
-
For some reason that is a common practice, my teacher in school told me it was red mercury and defeneded his position with gusto until i prooved him wrong... jackass...
Its red dyed alcohol isnt it? Mercuric oxide is yellow/red, mercuric iodide and suphide (rhombic) are red.. monoclinic mercuric sulphide is black. (or do i have these round the wrong way?)

well actually i don't know if it is red mercury or mercuric oxide
but i saw it i has the same charactarestics of the mercury
but in red
and that is what i want
so if you can help me whith that i'll be thankfull ;D

I used to to this in industry 15 years ago or so.
Mercuric oxide is a fine red powder, mercury is dissolved by slow addition into 98% HNO3 to get Mercury II Nitrate.
Mercury II Nitrate was loaded into in a furnace containing conc nitric acid (98%).
The contents are heated until the HNO3 has been used, resulting in red mercuric oxide.
The furnace is tilted and the powder dropped out into suitable plastic lined containers @25kg.
50/50 mixture of forty percent caustic and water was used as a scrubber for the fumes on both processes.

Red mercuric oxide doesn't have the same characteristics mercury has. And that was what the OP asked for.

Sorry, I thought I had, but by chemical change not an actual dye.

@RED_MERCURY
According to WIKI
Red mercury is a hoax substance
Tell us where you have seen it if you think WIKI is wrong.
If you mean a compound containing Mercury, please tell us the complete compound name you are looking to acquire.

Red Mercury is the MacGuffin in an episode of the third season of Spooks, a BBC series. I should have checked the Wiki entry before I tried to Google it on my own, because it is mentioned there. It was a good episode, in any case.

I think it is an interesting question as to how to dye mercury. Normally we don't really 'dye' metals, we just coat them in something colored and translucent. This obviously won't work for a liquid metal unless somehow the coating was liquid. This might work if the liquid coating could be made to tenaciously cling to the mercury.
It is difficult to color the interior bulk because your dye will be immiscible with mercury and will float to the surface readily due to the large difference in density. Presumably the only substances that would be sufficiently miscible would have to be capable of metallic bonding and be colored. I think that limits us to copper or gold among the elements. In any case this strategy isn't likely to work since you would need a very high proportion of colored metal and the resulting alloy would probably then no longer be a liquid.
It might be possible to color the bulk of mercury with a suspension. You would probably want nanoscale particles of dye and you would need to disperse them and stabilize them somehow against clumping or gelling. You would want them to be as close to the density of mercury as possible. You would need them to be very strong absorbers at the needed wavelengths and you would need a large amount in the mercury as only proportion at the literal surface would be active as light does not substantially penetrate metals before it is reflected. If the suspended particles tended to partition to the surface then you would need a lot less of them, but the high density at the surface might then be prone to clumping.
