Solid Ag with solid Au. it's done in process of producing 14 karat gold.
No, it dosent. If a base can be dissolved in water, its corresponding metal oxide must be able to be dissolved in water. So you see copper hydroxide is solid, which means it can't be dissolved in water. So copper oxide can't react or be dissolved in water to form copper hydroxide.
Copper is dissolved:2 FeCl3 + Cu = 2 FeCl2 + CuCl2
Mercury will form a thin film on a clean copper sheet, and in this form, is used to capture very fine or dissolved gold. And clean copper is very easy to solder.
Soda pop is a mild acid, because of dissolved carbon dioxide. Acid dissolves the copper oxide tarnish that darkens the penny's color.

Yes it dose .
Cu can be dissolved in many acids.

Yes it do But don't forget that it don't react with the Copper only
No. Instead, the magnesium ribbon is dissolved and metallic copper precipitates.
No. hydrogen will eliminate only copper, or gold in the oxidized state, and when dissolved. On 2nd thought, yes. Bring copper and gold into the oxidized, dissolved states, using aquq regia, a solution of 3 parts HCl with 1 part HNO3. Replace spare HNO3 with HCl, using 3 circles of HCl addition and vaporizing. Bubbling hydrogen at this point will free gold and leave copper dissolved

Blue is the solution's color When blue CuSO4.5H2O (copper(II) sulfate pentahydrate) is dissolved, the solution turns blue. When white CuSO4 (anhydrous copper(II) sulfate) is dissolved, the solution turns also blue.
Copper Sulphate mixed with hot water makes Copper Sulphate Crystals.
Copper acetate is a solid compound which can be either dissolved to form an aqueous solution, or if sufficiently heated will become a gas.
