The gold is only soluble in Aqua regia which is a mixture of one part Nitric acid and three parts Hydrochloric acid

Gold is soluble in cyanide. This sensitive method is used to leach gold from lowgrade ore. Ed
yes
Nothing; gold is not soluble in water. The colloidal gold is a more complicate problem.
The flakes of gold are more dense than water, therefore, it will sink to the bottom and then the water can be carefully poured out
No. Zinc is not soluble. It is a metal like gold is not soluble in water. There are some compounds of zinc like ZnCl that are soluble. I just learned this last unit in Chem class.

Cyanide is good for you. EAT IT!

No. Diamond is a pure form of carbon, and this is not soluble in mercury. Gold and silver may be amalgamated with mercury.
The nitrate anion is a large, monovalent moiety. Gold is also a fairly large cation, so, although the charge is +1, the effective attraction over that distance is somewhat lessened. These two factors make it easy for a polar solvent (like water) to separate gold nitrate into its respective ionic species. For the record, I cannot think of a single non-soluble nitrate compound.

Nothing. The gold remains the same. At room temperatures and pressures gold is extremely resistant to chemical reactions with oxygen and/or water. It is slightly soluble in water, but not so much that you'd notice. There are a few grams of gold dissolved in every million tons of seawater - its really not economical to extract. At very very high temparatures and pressures, such as are found thousands of metres underground, gold is slightly more soluble in water and thus is able to very slowly accumulate in quartz veins - which is the 'natural' form when veins of gold are discovered.
