Question

Quizplus · Accepted Answer

Silver (Ag) is below hydrogen (H) in the activity series, which means it is less reactive than hydrogen. Therefore, it will not be oxidized by hydrochloric acid, which is a reducing agent that produces hydrogen gas (H2) and the corresponding metal chloride. All the other metals (Al, Fe, Ni, and Mg) are above hydrogen in the activity series and will be oxidized by hydrochloric acid to varying degrees.
