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+.
Alkali metal hydroxides are strong bases that are highly water-soluble, forming alkaline solutions. Alkaline earth metal hydroxides are also bases but are less soluble in water compared to alkali metal hydroxides, resulting in less alkaline solutions.
Metal hydroxides make alkaline solutions.(e.g sodium hydroxide) Pascal
Yes. The magnesium metal replaces the copper in the copper sulfate. This is a single replacement or single displacement reaction.
The reaction occurs because iron is more reactive then the copper is. The more reactive metal wants to create a compound, which is why it forms iron chloride. Copper, being the less reactive substance wants to become pure and separates from the chloride to be on its own.
The product of iron and copper (II) sulfate is iron (II) sulfate and copper. This reaction is a single displacement reaction where the more reactive metal (iron) displaces the less reactive metal (copper) from the compound.

Magnesium is the alkaline earth metal that is part of the reaction process of photosynthesis.
Magnesium is the alkaline earth metal that is part of the reaction process of photosynthesis.
No, copper is not an alkaline earth metal. It is a transition metal that is commonly used in electrical wiring and plumbing due to its excellent conductivity and corrosion resistance. Alkaline earth metals include elements like calcium and magnesium.
Alkali metal hydroxides are strong bases that are highly water-soluble, forming alkaline solutions. Alkaline earth metal hydroxides are also bases but are less soluble in water compared to alkali metal hydroxides, resulting in less alkaline solutions.
Yes, iron can displace copper from solutions of its salts through a displacement reaction. Iron has a higher reactivity than copper, so it can replace copper in the salt solution, forming iron salts and copper metal.
Yes, metal can react with copper chloride to form a displacement reaction. Depending on the reactivity of the metal, it can displace copper from copper chloride, forming a new metal chloride and copper metal. The reaction will vary depending on the specific metal used.
Alloy
electroplating onto a more reactive metal, such as iron or zinc, which displaces the copper ions from the solution, forming a solid copper coating. This is known as cementation or displacement reaction.
When copper carbonate reacts with potassium, it forms copper metal and potassium carbonate. This reaction is a redox reaction where copper is reduced and potassium is oxidized.
Metal hydroxides make alkaline solutions.(e.g sodium hydroxide) Pascal
No, halogens are a group of non-metal elements that are part of the periodic table. They are not alkaline solutions; in fact, they tend to form acidic solutions when they react with water.
