The described scenario depicts a neutralization reaction. This chemical process involves the combination of an acid and a base to produce a salt and water. In this specific case, the reaction results in the formation of copper(II) chloride, accompanied by a change in solution color to blue-green.

The scenario describes a single displacement or replacement reaction, specifically a metal-acid reaction. In this type of reaction, a metal reacts with an acid to form a salt and hydrogen gas. The metal displaces the hydrogen ions in the acid, leading to the formation of the corresponding salt and the release of hydrogen gas. The general form of this reaction is:
Metal + Acid → Salt + Hydrogen gas
This displacement reaction is characteristic of metals with a higher reactivity displacing hydrogen from acids and is a common example of redox chemistry.
