yes
Because sodium is not as stable as copper.
Metallic copper does not react with sodium hydroxide. But if sodium hydroxide is added into a solution of copper ions, it would form Copper(II) Hydroxide. It is a precipitate which is insoluble in water.
The question isn't very specific (preferred for what?!), but sodium metal is less reactive than potassium. It is also slightly more abundant than potassium on Earth.
Sodium chloride is a salt and copper is an element.
The reaction between sodium hydroxide and copper sulfate forms copper hydroxide and sodium sulfate. Copper hydroxide is initially formed as a blue precipitate, which can further react to form copper oxide upon heating.
The reaction between sodium hydroxide and copper sulfate will result in the formation of sodium sulfate and copper hydroxide. The products of this reaction will be a blue precipitate of copper hydroxide and a solution of sodium sulfate.
If you add copper sulfate to sodium hydroxide, a double displacement reaction will occur. The copper sulfate will react with the sodium hydroxide to form copper hydroxide, which is a blue solid, and sodium sulfate, which is a soluble compound. This reaction is often used in qualitative analysis to test for the presence of copper ions.
The reaction between sodium hypochlorite and copper results in the formation of copper(II) oxide and sodium chloride. This is an oxidation-reduction reaction where the sodium hypochlorite oxidizes the copper metal to form copper oxide and is itself reduced to sodium chloride.
Copper and molten sodium chloride are electrical conductors.
Copper is corroded in a sodium chloride solution; CuCl2 is formed.
When you heat copper hydroxide and sodium nitrate, a chemical reaction occurs where the copper hydroxide decomposes to form copper oxide and water, while the sodium nitrate decomposes to form sodium nitrite, oxygen gas, and nitrogen dioxide gas.
Copper(II) carbonate is insoluble in water and doesn't react with sodium sulfate. A green product, visible on ald objects made from copper or copper alloys, is a mixture of copper carbonate and copper hydroxide.
