Answer:

A. chromium 3+ ion

Step-by-step explanation:

The activity series shows that chromium will be oxidized to chromium 3+ ions. This series shows the reactivity of each metal relative to one another.

It is used to predict the activity of metals.

  • From the series, chromium like most metal will favor an oxidation reaction;

Cr ⇄ Cr³⁺ + 3e⁻

The more oxidized metals are located at the top of the series.
