a gold metal cyclinder with a density of 8 g/ml would be what kind of metal?

You might be referring to brass, which has a density of 8.5 g/ml.\n\nBronze with 11% tin has a density of 8.1 g/ml.\n\n\nI would guess the brass, since it is more commonly used.

copper and gold are soft, and they have low melting point.

I don't know how you are precipitating out the gold, but I don't think a colorimetric test for gold in solution is possible.  It is non-reactive and does not ionize.  Given that gold has filled upper electron orbitals, you might be able to run a UV-VIS spectrum and get some UV absorption for solvated gold versus clean aqua regia.  The UV apsorption is probably going to be in the lower UV wavlengths, and it might not be possible to differentiate between trace levels of gold and trace levels of transition metal impurities.\n\nIf you are precipitating the gold by an equilibrium process, just load up on your precipitation compound to push the equilibrium as far as possible to one side.  Another possibility is to electrolytically remove any trace gold from the aqua regia.  Sorry I don't have any better suggestions.

Iridium, a metal of the platinum family, is white, similar to platinum, The specific gravity of iridium is only very slightly lower than osmium, which is generally credited as the heaviest known element. Calculations of the densities of iridium and osmium from the space lattices give values of 22.65 and 22.61 g/cm^3, respectively. These values may be more reliable than actual physical measurements. At present, therefore, we know that either iridium or osmium is the densest known element, but the data do not yet allow selection between the two. Although its principal use is as a hardening agent for platinum, iridium is also used to make crucibles and devices requiring high temperatures. It is also used for electrical contacts. \nThe element forms an alloy with osmium which is used for tipping pens and compass bearings.

pllatinum is not white gold. The pure element Au is not white gold. \n\nWhite gold is an alloy of gold mixed with white metals such as nickel, silver, and palladium. Like yellow gold, white gold glitters in a variety of carats: 18ct, 14ct, or 9ct. \n\nEighteen-carat white gold consists of 75% gold mixed with 25% white metals. New white gold rings are usually coated with a hard protective finish of rhodium, a silver-white metal like platinum. To keep a white gold ring looking its best, Gillett's recommends an annual replating of rhodium, since the coating wears off over time. \n\nPlatinum, an entirely different element than gold, is a white metal that is denser, heavier, and longer-wearing than gold. It's usually used in almost pure form and does not require a protective coating. Platinum is quite expensive, a platinum ring is perhaps twice the price of a similar ring made in white gold.

Depending upon whether it is metallic mercury or a mercury compound, different rules apply.\nYou can get some ideas at the site below:

Yup.  According to the electrochemical series, the Au3+ ion (in order to plate itself, gold must first be converted to an ion from an anode in an electrochemical cell: how that is so is another question...) is a relatively good oxidizing agent (which means itself gets reduced) when compared with other metals at least.  You can check this by seeing its standard reduction potential.  Standard reduction potential for gold is +1.50 eV while that of Fe(steel is mostly iron) is only ) 0.77eV.  The rule is that, the metal with the greater reduction potential gets plated on the one with less potential.\n\nCheck this link for a better understanding. http://en.wikipedia.org/wiki/Image:Srptable.JPG

You need a solution of gold sulfate or gold chloride to do it, but it has to be extremely pure, made with distilled/deionized water.  Remember to have your ring on the anion (the negative) and your gold source on the cation.

yes, with an alloy or equal or lower melting point

It would depend on how much you have.\nWhich is heavier, a pound of feathers or a pound of rocks?\n-They weigh the same.\n\nLead has a density of about 11.3 grams per cc,\nGold has a density of about 19.3 grams per cc,\nso for a given volume, gold is much heavier than lead.

Gold would be deposited on the surface of the lead.\n\n3Pb + 2Au(NO3)3 ---> 3Pb(NO3)2 + 2Au

A ductile substance is easily pulled or stretched into a thin wire without breaking.\n\n"...gold is the most ductile metal and one gram of it can be drawn into a wire 2,300 meters long."\n\n"The order of ductility of some familiar metals is gold > silver > platinum > iron > copper > palladium > aluminum > zinc > tin > lead"

Very hard to say without more of a description, but the first thing that camr to mind is a tortoise beetle. Some look clear and I've found some that look like they are made of pure shiny gold.\nA picture at the link below.

Assuming this is fine gold with a purity of 99.9% or better...\n\nThe current spot price of gold is: $718.40/Troy Ounce. (May 14, 2006)\n\n1 troy ounce = 31.1034768 grams\n\nSo, .8 grams = 0.02572059 troy ounces.\n0.02572059 * $718.40 = $18.48\n\nSo: $18.48, but not many people would buy such a small amount of gold unless you drop the price by about 10%, so your could probably sell it for: $16.63
