Solution:
Copper is a metal that would not react with dilute hydrochloric acid. The reaction of metals with acids is:Metals generally react with dilute acids to produce hydrogen gas. Hydrogen gas is released in this reaction. But not all metals give this reaction; because of its low reactivity, Copper does not react with dilute acids. It cannot displace the hydrogen from the acidic solution. Magnesium, Iron, and Aluminium are more reactive than Copper; therefore, they will react with to form salt and hydrogen gas.
