Question

Which metals do not react with dilute hydrochloric acid?

Answer 1

Reactivity series

• The arrangement of metals in descending order of their reactivities is referred to as the "metal reactivity series," sometimes known as the "activity series."
• To determine if a metal can displace another in a single displacement reaction, one can use the information offered by the reactivity series.
• It can also be used to find out reactivity of metals toward water and acids.

Metals that do not react with dilute hydrochloric acid

• Metals that do not react with dilute Hydrochloric acid$\left(\mathrm{HCl}\right)$ are copper, silver, gold, and mercury.
• It is because they come after hydrogen in the activity series.
• So, these metals can't replace hydrogen from hydrochloric acid.
