* Copper is relatively unreactive: Copper is a noble metal, meaning it is relatively resistant to corrosion and chemical reactions.

* Alkali reactions: Most alkali reactions involve the formation of a hydroxide ion (OH-) which can then react with a metal to form a metal hydroxide and release hydrogen gas.

* Copper and hydroxide: Copper is not easily oxidized by hydroxide ions under normal conditions. This is because copper has a relatively high standard reduction potential, making it less likely to lose electrons and form ions.

However, there are some exceptions:

* Strong oxidizing alkalis: In the presence of very strong oxidizing alkalis, like a hot concentrated solution of sodium hydroxide (NaOH) with an oxidizing agent like hydrogen peroxide, copper can react to form copper(II) oxide. This is a slow reaction, but it does occur.

* Ammonia: Copper can react with ammonia in the presence of oxygen to form a complex ion called tetraamminecopper(II) ([Cu(NH₃)₄]²⁺). This reaction is used in the production of copper-ammonia solutions, which have various industrial applications.

Overall, while copper does not react quickly with most alkalis, it can react under certain conditions.
