In basic conditions copper typically forms a hydroxide precipitate (copper (II) is hexadentate and so is octadehral). Alkalis (such as NaOH) and dilute lewis bases (such as ammonia) will produce the precipitate. The net reaction could be summarised:
Cu(s) + 2OH-+ 4H2O → [Cu(H2O)4(OH)2](s)
The aqueous copper can ligate with lewis bases. Excess ammonia would produce the following reaction:
[Cu(H2O)4(OH)2](s) + 4NH3 → [Cu(NH3)4(H2O)2]2+(aq)+ 2OH- + 2H2O
In a similar way copper metal can react with carbonate ions to form CuCO3. Similar to the example of ammonia above, there are other lewis bases that can result in ligand exchange (chloride and Iodide are two such examples).
Note: The above examples all involve copper (II) / Cu2+. Copper (I) compounds do not readily form in solution as it will disproportinate to form Cu and Cu2+.

What do non metal oxides dissolve in water to form?
Whichofthefollowingisclosesttotheaveragemassofoneatomofcopper?(Cu=63.55
What do metal hydroxides make when they dissolve in water?
Metal hydroxides make alkaline solutions.(e.g sodium hydroxide) Pascal
Was a strip of magnesium metal into a solution of copper sulfate a chemical change?
Yes. The magnesium metal replaces the copper in the copper sulfate. This is a single replacement or single displacement reaction.
Does copper ll chloride conduct electricity in the aqueous state?
Copper II chloride (CuCl2) is an ionic compound because copper is a metal and chloride is a non-metal. Like all ionic compounds in aqueous solutions (i.e., dissolved in water), it conducts electricity.
What is the family name that calcium is in?
Group 2 (alkaline earth metals): lithium, sodium, potassium, caesium, rubidium, francium.
Is copper an alkinline earth metal?
No copper is not an alkaline earth metal because it is not in the group 2A.Only group 2A elements are called alkaline earth metal.
Which alkaline earth metal is part of the reaction of photosynthesis?

Which process is changing copper oxide into copper metal belong to?
it is a reduction reaction
What is the reaction o copper and ammonia?
Copper is a metal element. It is not reacting with ammonia.
What do metal hydroxides make when they dissolve in water?
Metal hydroxides make alkaline solutions.(e.g sodium hydroxide) Pascal
Why is the magnesium the most reactive metal among silver copper lead zinc and iron?
magnesium is an alkaline earth metal. silver, copper, lead, zinc, and iron are transition metals. alkaline earths are naturally more reactive then transition metals.
